BaseQiAluminum microSD Adapter for MacBook Air 13" and MacBook Pro 13"/15" (Non-Retina) Models

The product works as advertised. But some tips for a flawless experience:1.) BaseQi produces different addapters for different computers. Is not One-Size-Fits-All. Therefore, this product will Work on 13"Airs but NOT on 11"Airs, or surfacebook or others. You have to read VERY carefully and select adequately. Efectively, the product sits flush and discrete on my MacBook Air 13" Early 2015. And It's easy on the eyes (i.e. It looks good)2.) Some of the "Negative Reviews" state that the product may burn the MicroSD. While I find that hard to believe, just in case I tested it first with some Known Good MicroSD cards I do not care About (2GB) using AJA System Test. You know you have MicroSDs like those lying around between the sofa's cushions. Use them!3.) All that testing also meant I had to insert and retrieve a couple of times. The "ToolLess" mechanism works as advertised (a fingernail is all I need, but YMMV).4.) I used it, along with a 200GB U-3 MicroSD to move all my steam collection, and used a Symbolic Link. This is important because, if there were instabilities (i.e. the addpater disconected) the simlink would break, and that has not happened. Mind you, I haven't moved the machine around, but seems to be stable.Overall, quick and easy way to expand your storage without paying the high priced Apple charges for their PCI-e SSD. Just bear in mind that, even if you use any of the future V60 or V90 cards that are currently i the works, it will still be slower than the indernal drive. Specially for Writes. So, is best if the data here is Write once read a lot. Or write little read a lot (like, for instance, steam games ;-) ).End of Jul 2017 update: If the laptop goes to hybernation, the SD card disconnects. I believe this is more a problem of the OSX/MicroSD card combo, and not a problem of the adapter Per-Se. extracting and reinserting the adapter takes care of any issues, and since this is a tooless adapter, is pretty simple to do. If you get a different MicroSD (or an OSX Update works some miracle), this may not affect yu. Still a Great product.

this was the best money I spent on that

This was everything I was hoping for. I'm a DJ and I needed a way to expand the internal storage of my MacBook Air without having to open it up or buy a more expensive version. This little gadget was the perfect answer to my first-world problem. I ordered a high capacity microSDXC card and put my whole DJ music collection on there and it's worked flawlessly ever since. The drive is always recognized upon booting up the laptop and the performance is perfectly fine for my needs (obviously that's mostly related to the brand/model of microSDXC card you use). Lastly, I love that it's aluminum and fits flush with the body of the Macbook. It looks like it was designed to be there. Lastly, it fits very snugly. That's a good thing as there's no fear of it falling out. I recently upgraded my microSDXC card to a higher capacity model and had to pull this thing out for the first time. After nearly destroying a credit card trying to pry it out, I decided to take a breath and pull out my iFixit tool kit and used the correct tool to easily pry it out (metal spudger). Go figure, the swap went perfectly with the right tool. This thing is the best.

I purchased this item to install in a 2012 MacBook Pro non-retina to provide some extra shared storage between the OSX and Windows 10 partitions. It took some doing to get the card reader working properly in Windows, but that is definitely not the fault of the adapter. I was able to get the adapter and microSD card recognized properly in both Windows and OSX but occasionally OSX will claim that the microSD card is not recognizable and offer to initialize it for me. I don't know where the fault lies but I then have to boot into Windows to scan and repair the card before it will be usable in OSX again. The card is formatted NTFS for compatibility reasons, and works fine 95% of the time. I have not experienced any data loss, just the need to "repair" the card in Windows on some occasions. 4 star rating instead of 5 star simply because I know I'm a rare use case, but this setup has provided me with some difficulties while using a standard SD card did not have any issues.

Great item - an incredible way to increase storage.Being flush with the laptop body is very important to me.Easy to remove with your fingernail.NOTE: Make sure you buy the correct version. There are a few kinds.

My MicroSD card would only go in half way. I then contacted BASEQI about the issue and they accused me of inserting the card upside-down, like I could not tell the difference, or would not have tried both orientations before contacting them. They required me to send photographic proof that I was inserting the card properly. It then took them 2 days to reply. The reply was to the effect that it didn't happen to other customers, and I got a basic brush off. After several more days with no reply, I pried the unit open carefully loosening the glue that held it together. The photograph shows what I found. It was clearly defective and they decided customer service meant making accusations and ignoring rather than offering a replacement up front.The paint missing from the MicroSD card is due to them suggesting I force it. I only forced it about .5mm more and there was no more to give. It was then wedged so hard I had to use needle nose pliers to remove the card. The pliers removed the paint from my MicroSD card in the process.These things have a very specific use case, and it may not be possible to find a replacement that does the same thing. Possibly that is why BASEQI feels they can get away with such appalling support. Regardless, if you can avoid purchasing from BASEQI, I would recommend you do so. Just so you know the source of said advice, I am a 30+ year IT veteran. Dealing with stuff like this is something I do daily.
