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

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.

I am so impressed with this Micro SD Adaptor. Not only it fits in my Dell XPS15, 9560, but it is very well made. It is much more expansive than other micro SD adapters. The card is little bit shorter (about 0.5mm) than the depth of the SD card slot (see attached photo) because it is not made for the XPS15, 9560, but it is not a problem. There is no problem removing it from the laptop with you finger nail. The manufacturer is not planning to make a custom fitting card adapter for the new Dell XPS15, 956-0, so you have to settle for this adapter if you are looking for flush fitting Micro SD Adapter. When buying this adapter, make sure to get the right model (103A). The other models made by BaseQi are either too short or too long or do not fit at all.Prior to buying this, I bought a very inexpensive plastic adapter, and it destroyed the SD card slot's internal card contacts on the first try. I had to replace the laptop motherboard to correct the damaged card slot. Yes, the card reader slot is embedded on the motherboard, so there was no other solution but replacing the entire motherboard. Yes, it was an over $1,000.00 mistake. You get what you pay for.I am very happy with this product.

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.
