Masterbuilt® Gravity Series® 800 Smoker Grill - Charcoal Grill plus Griddle Insert, Digital Control, App Connectivity, 800 Cooking Square Inches in Black, Model MB20040221

I've had my Masterbuilt 800 for 6 weeks now. The gravity feed charcoal is a game changing design for me. You can layer the charcoal box with charcoal or charcoal wood, then wood pieces for smoking, then charcoal, etc. And the ash bucket is at the bottom and makes clean-up a snap. Assembly wasn't too bad. It may take you longer than you plan on so give yourself plenty of time. After assembly, be sure to season the grill correctly. Check out the videos on youtube for assistance. There is tons of information available. I know, because I think I watched them all. LOL I did make the most perfect smoked ribs I ever had. Along with grond beef jerkey, chicken, pork chops, wings, and fish. You can literally smoke something for a couple of hours, then turn up the grill to 700 degrees for finalizing cooking or searing if necessary. In about 7 minutes it will be up to temp from 250 degrees. No matter what temperature you set its pretty even and doesn't divate much at all. However be aware, like any other grills, there are your hot and cool spots inside. The griddle is a nice touch. The cooking manifold swtches out in about 30 seconds, and the griddle is HEAVY and a perfect surface to cook on and attaches easily. You shoud by some griddlle accessories for cooking on it however. I made smash burgers and they came out good and smelled up the neighborhood.. "cheezee bugar cheezee bugar, Pepsi, no Coke... I think it was the grilled onions. The control panel works well, but for some reason, somewhere between the time you turn it on and about 5 to 10 miutes later, the blower turns off and you have to repower the panel by turning it on and off. It works fine after that, but it has happenned 3 times already. Just be sure to monitor it at first until you get used to using it. I did download the app for operating the temp and timer from my phone. That worked well at first, but it is bluetooth, so if you walk away to far with your phone in your pocket you may loose connection and the fan will turn off. I generally don't use the app since I like to be outside with a beer and cigar when I'm queing. If your "on the fence" about buying one... don't be. You won't be sorry. I had a Trager pellet grill I bought 7 years ago. It was ok, but never really got the smoke taste I was missing like using the Masterbuilt. Plus, you cant sear with it, and it doesn't come with a GRIDDLE. Lastly, if you made it this far, search Masterbuilt mods. They're aftermarket accessories specifically for the grill. I bought the whole shebang before I put it together and am glad I did. If you have extra money do your research and get that also. Hope this helps. Happy grilling.

VERY happy with how this works once I get it up and running. It regulates temperature excellently and gives great-tasting meat. I am concerned, however, about the electronics. The blue-tooth / wifi worked until about half way through my first cooking (was slow-cooking a roast, so this was a several-hour affair), but then stopped working and I have not been able to get it to pair with either my iPhone of iPad since. Also, as I was starting my second cooking, the unit would not turn on. I checked all the connections, which seemed sound, but it still would not turn on. Finally, after I pressed the on button several times, it did come on and worked fine (except no blue tooth or wifi). Non-function of the remote capabilities is not a big deal: I'm pretty much always near the grill when using it anyway. However, I'm concerned about the control box in general: Is this finicky nature an indication that it may stop working soon? Again, that is my only concern. Otherwise, this is an amazing grill and I am very happy with it. 9/2/24 update: Continues to work, usually even with Wifi. It is still finnicky, but I can consistently get it to work. Masterbuilt actually contacted me with pointers, and then sent me a new control box. I have not installed it yet since I can always get the original one to work, but it is very nice to know I have it in case. EXCELLENT customer support, I would say.

We so wanted this grill to be the crème de le crème of grills. The ultimate grill for serious grill masters. This grill is the absolute perfect CONCEPT BUT WITH A FATAL FLAW DESIGN. We loved the fact that this grill could get up too 700 degrees and is gravity fed charcoal. You could cook a ton of stuff on it….if it worked properly. THE PROBLEM: It will only work as stated for the first 20 min- ie.,it will heat up, Fan will turn on until it gets to desired temp and then turn off until it drops 10-15 degrees, then back on to maintain that desired temp BUT FOR A SHORT PERIOD OF TIME of 20 min. AFTER THAT….the fan shuts off AND DOES NOT COME BACK ON until it reaches all the way down to 100 degrees F all the while you have your chicken or whatever else you are cooking is just sitting there on the grill barely warm. There are two side vents to help regulate the temp/fan as well, but even then, the fan stays off until it goes back to 100F. The temp sensor can connect to Bluetooth if you desire to troubleshoot. We’ve tried cooking on this grill several times even showing it off to friends and family because my husband was soooo excited about the ultimate design. We have tried cooking meat on this grill several times and it does the same thing over and over. We’ve had to always finish cooking out meat in the oven d/t it partially cooked because the grill fan continually shuts off after 15-20 min and does not turn back on until it gets all the way down to 100 degrees-clearly not enough heat to cook our meat. Forget it if you have a large party or want to smoke ribs or a pork butt. It will take hours and hours and nothing but a big fat embarassment. It’s like having a Tesla that loses its charge driving down the road…expensive, nice concept, but worthless if you want to eat dinner before 10pm. The irregular temp control makes thr meat unevenly cooked, under and over as you constantly have to troubleshoot the temp. We’ve watched countless YouTube videos, emailed customer service several times, and tried to contact a live person. They have very poor customer service, as it’s virtually impossible to get ahold of anyone except via email and they make you jump through multiple hoops by locating the serial number and taking a photo and sending in a receipt to prove you actually own the grill BEFORE YOU CAN EVEN SEND AN EMAIL TO GET HELP! The grill’s biggest defect is in the apparatus that controls the fan and temperature. We received quite lame email instructions back for trouble-shooting. Our first email back simply described how the fan and temp gauge worked, Duh! The third email stated how to reset the trmo sensor with WiFi or to make sure the proper codes were showing. I finally just emailed them to tell them we’d tried everything as my husband was willing to do everything within his power to get this grill to work properly. ONLY AFTER I SAID WE ARE RETURNING IT (as I was within a 2 day window of not being able to return back to Amazon)did the customer rep from masterbuilt call us as we’d left our number in the first email 2 weeks prior. He only said “well…I don’t know. Sorry”. That’s it. I’ve heard horror stories where others bought their grills on the Masterbuilt site and they put people off until the window is expired to return it. You must register this product with Masterbuilt in order to have parts covered under the one year warranty. This does not guarantee you can return it. Luckily, I returned it to Amazon within the allotted time frame for a full refund! Whew! I barely made it and would have been out almost $800 if not. Overall, this grill would be the bomb if the fan and temp sensor would regulate properly, otherwise you cannot use it like a regular grill since it’s gravity-fed. It’s rendered useless. Sadly, to my husbands disappointment, the customer service was so poor that we had no choice but to return it in time to get our money back. Hopefully one day someone can make it work. All other reviews on grills similar to this seem to have the epic fail between the fan and temp sensor-thereby, doesn’t work.

I purchased the Masterbuilt Gravity Series 800 in December '24. I could not be more pleased with the performance of this amazing bbq smoker! Its construction is very solid overall (thick structural steel in legs, lid, outside of hopper and pans); however the charcoal burning section of the hopper (firebox) is relatively weak and not durable in the long run (thin stainless steel walls that will corrode in a few years of weekly or bi-weekly use). While this chamber has ceramic heat insulation panels behind the original firebox plates, this is insufficient for the very high temperature produced there. Fortunately, in the market there are modifications that make the Masterbuilt Gravity Series a true bbq war machine. As soon as I received the equipment, I bought some accessories from LSS mods (firebox, hopper cover, inlet grate for hopper, super-sear manifold with base and cover and ash bucket grate). I have posted some pictures of the "overhauling" process of this beautiful bbq smoker. Additionally, I have sealed the hopper gaskets with a high temperature sealant (Kraken), replaced the default thermometer with a beautiful Lavalock (3 in. Face, 3 in Stem, M8 Thread), purchased the Levain & Co Meat Temperature and Smoking Temperature Magnets, and modified the left service tray by making it hinged (for easy storage). Check out the video I uploaded! ;) With these modifications I'm sure I will extend the longevity of the smoker for many years to come! I can't wait to try the pizza oven accessory! I will keep you posted! :)

From What I can tell so far this grill will do what I had hoped. I also have the pizza insert which will be our first cook today. I went through burn off and seasoning cycles and was impressed with the speed of heat and smoke volume. I chose this grill because my Camp Chef pellet grill could not reach the heats I wanted. Unfortunately, I have to remove a star because of the complicated assembly. I did have delivery with free assembly, but it took 2 people over 2 hours while referencing online videos. I do not fault the assembly crew for this. They showed up early and did their best. It just seems to me that the assembly requires much more than I would expect from a product. I am very glad it had assembly because I am not sure I could have done it myself. The assembly crew were not perfect. I see several issues where they made mistakes. One of which will require me to disassemble the hopper to fix (the little guide for the fan baffle is not extended). They also lost one of the warming grates in the packaging I guess. I did not notice it missing until they were gone. I probably will never need both warming racks.

Update: Finally got one that wasn't damaged and had it assembled, so far I've only used the griddle which definitely has hot-spot issues but they're easy enough to manage. Once lit, the grill does change temperature very quickly and maintains temperature well. I spent extra and bought the mod kit to strengthen the fire box and what not after reading other reviews of it wearing out quickly. I haven't had a chance to try the the wireless yet. While it's a lot easier than a normal charcoal grill, I'm not sure that I would spend the money again if I had to do it all over. Didn't get to use or even see it assembled. It was delivered, box looked mostly fine, but when the assembler removed everything and checked it all, the underside was damaged, and the side dented. Not light cosmetic damage, damaged as in the rivets busted and was unusable. Naturally it's out of stock as well so a replacement can't even be sent, I just have to keep watching for it to be in stock and hope the price is the same, as well as hope it won't be damaged as well. If I ever get one I can actually use, I might update my review.

Ok, I was extremely hesitant to purchase this Digital smoker. However after several uses this item has proved to be a very resourceful piece of equipment. The key is the temperature control being consistent with very little variables in the heat. Like any barbecue it has its hotspots on the grill. But any educated smoker knows these locations on their barbecue and places they appropriate food in these areas to get a consistent cook temp. Overall the temperature control is unprecedented. With the new update on the Bluetooth software it connects easily with Both android and Apple devices. Also, the app is extremely’s easy to use. Straight to the point, temp and time! Now I’ll talk about the best part of this smoker and that is the searing at 700°. You go from a low to 250° to a high 700° in just a minute. It’s great for tri-tips that you want to smoke and then seer. Not to mention the incredible burgers and steaks you can get out of this thing. If there were any negatives it would be the process of putting it together. One part in particular is the screws for the lift bar on the main door. Very easily dropped into the inside body of the door void. But, with a little work you can get it back out. I did far too much research on this barbecue before buying it and watched a lot of reviews over the last year. There is a lot of negatives towards shipping and manufacturing defects. And a lot of negatives towards dealing with Manufacturing warranty. I have not myself experienced any of these issues and I would HIGHLY recommend this product. KNOW YOUR BBQ There is a great deal of value in this item for what it does. It is not a heavy cast iron built BBQ meant to last 100 years in the rain. If you know Master Built Products you know they use thin metal body’s , however they double wall the majority of areas required to contain heat and consistency. This bbq requires cleaning on a routine basis to maintain consistency in your cooked and to reduce GREASE FIRES. Remember this thing can get up to 700° after you’ve just cooked a pork butt for 10hr. I recommend using aluminum foil pans on the bottom rack and use the second rack for meat on your long smokes to reduce grease drippings on the manifold burner.

I purchased this as a gift for my boyfriend, who has been into smoking meat for several years. Previously he had a tower-style smoker, but gave it away to a friend because he didn't really like it. So we have been looking around at all the options, and he kept coming back to this one. I won't lie, it was a big pain to put together. You definitely want someone to help if at all possible, and allow extra time. There are a lot of parts. At one point one of the washers fell INTO the grill lid (between the outer and inner metal pieces is about a half inch of hollow space), so that was fun to fish out. However, once it was put together it's really easy to use. The only real problem we've had so far is when the charcoal in the hopper gets somewhat damp. So if possible, I'd recommend removing unused charcoal after everything cools off if you're not planning on using it for a while. If your charcoal is damp, it will take a while to light, but we've always gotten it going eventually. You will also definitely need fire starters to get it going (the Masterbuilt brand works great and they're pretty cheap). We also had to tighten the bolt for the ash tray door in order to keep the fan working correctly (the fan will shut off if it senses this door is not shut, so we had to tighten it). Also, just to reiterate all the other reviews that mention it because it's not really super-clear in the assembly instructions: The two metal slides that go in between the hopper and the grill? Those are for STOPPING the airflow, thus STOPPING the heat, so make sure they are OUT when you are using it! The flavor is much better than a pellet grill, and I would say it's equally easy to use once you get the hang of it. There's definitely more smoke flavor. Adding wood chunks to the ash tray for flavor is easy and you can play around with whatever combination you like. The app is also nice for monitoring temperature from, say, inside the nice air-conditioned house :)

I finally upgraded from my old Masterbuilt Barrel Smoker and I knew I could count on a quality product and great customer service. If you like to grill and smoke with charcoal the Masterbuilt Gravity Series is for you. Low and slow or high and sear, it doesn't matter your results will be perfect. Load up the hopper with lump charcoal, add a few wood chunks throughout, set the desired temperature and let the magic happen.

Very versatile

J'adore mon nouveau Masterbuilt je le recommande fortement

the smoker listed as a smoker grill assembly but the grill was missing-disapointing as it was expensive and no one returned my request to have the concern corrected
