SYACOT Auto Spout Lid for Hydro Flask Wide Mouth Water Bottles, Replacement Top Spout Lid for HydroFlask Wide Mouth 12 oz 32 oz 40 oz, Chug Cap with Flexible Handle,Big Nozzle

We've only had these for a short time but so far so good. They fit our 32oz wide mouth stainless steel bottles really well whereas the openings on the 32oz plastic bottles with the motivational time/ounce markers on the sides have a slightly larger diameter and different threading and therefore do not work at all (see pic). Incidentally, the stainless steel bottles can also take wide mouth Nalgene bottle lids, so I'd expect that these lids would work for wide mouth Nalgene bottles as well. I am also happy to report both of the seals on these lids can be removed for thorough cleaning. This is always a concern for me because dirt, bacteria, and water get trapped underneath these seals and no matter how careful I am with other lids, mold eventually begins to form under them. Fortunately, with these lids both the rubber gasket on the underside of the flip up part and the ring on the inside of the threaded part come out. (The ring took a little bit of careful work with a toothpick and some patience, but it did eventually come out.) We haven't experienced any leaks with these yet. As for durability, they seem to be pretty well made, but only time will tell. Fingers crossed that these will last.

it works as it should, dosent leak, easy to clean and the handle is a little longer which is nice. good product :)

Lid that arrived appeared to be used. It was moldy, dusty and broken. This was supposed to replace one of my old one that I have used everyday for over a year. Update: Replacement arrived in good condition.

Update (October 2025) ** Have used these pretty constantly since the middle of LAST YEAR. Only now am I thinking of replacing these ... because they are starting to wear out. Both lids are not latching all the way 100% of the time, and water leaks a bit from the rubber rings under the lid. For over a year of pretty regular use, washing, and using daily, they held up well for only being less than $16.00. Original Post (2024) **Water tight and works well even after a few months of use. **Doesn't screw as tightly down as the name brand. ** Give it an extra squeeze while putting the lid on and it will hold well.

Was a little worried if these would be good quality or not but they are great. The feel very sturdy and perfectly fit my 40 oz hydroflask. The seal is perfect and the plastic is nice and thick. I am sure these will last a good long time.

In theory, I love how this thing works, but the button to open the actual spout is WAY too sensitive. Sometimes trying to move it from lock to unlock will spring the bottle open, which is fine; if you're unlocking it, one could assume that you're going to take a drink anyway. However, I've notice that BARELY touching the button when it is in the unlock position will open it as well. I've had this laying on my car seat and I threw my wallet next to it, and it just happened to hit the button and the lid flung open and spilled water all over the car seat. I've also had it open while in my bag as well. These are totally anecdotal, and I understand that I could've easily used the lock position, but the latch shouldn't be so sensitive. Other than everything mentioned above, it's a solid lid for the money, but I just have a gripe with the sensitivity of the button. Update: once again, this lid has managed to dump water all over my belongings, including some electronics, while inside my bag. The button on this lid needs to be redesigned, badly. Changing from 3 stars to 1...

Good quality and perfect fit. Does not leak.

Doesn't leak. Able yo lock and unlock the spout. Perfect, better than having a twist off lid. Easy, push the button and the lid pops up. Push the cap down and it clicks in place. Slide the button up and it locks the lid down so no unfortunate mishap. Perfect. Definitely buying more for my wife's containers.
