BASEQI Aluminum MicroSD Adapter for Microsoft Surface Book 13.5" (Model-350A) - Add up to 1TB of extra storage space

It is an awesome product. I now have my memory card installed on my computer and it is completely flush with the case. Having previously lost a card I am glad to have this adaptor

So I can vouch that this little adapter is quite functional and effective as a purchase still in 2022. Rather than buying the latest iPad, I realized that for my needs the older Surface Book 2 was a better fit for my primary uses. So with a simple, high quality 512MB mini SD card (separate purchase) and this adapter, was able to quickly expand the memory of my rig. (The card I purchased was already formatted, but I re-formatted it so that the card would not be recognized as removable storage but viewed as an internal drive (like a partition / folder but treated as single unit, as some software doesn't play well with saving to removable storage).From comments when I was researching the product, it seems that some customers may have inserted it the wrong way and forced it, in some cases causing damage. Just take a moment to ensure you have it aligned the right way and insert it gently, doesn't need to be forced. It sits flush and blends in quite well from a design / aesthetic perspective. Very pleased with this purchase and highly recommend it. On a related note, I also purchased the Skinomi full body protector (film), also available here on Amazon, as bit of sleek and effective protection. Also highly recommended.

Very recently, my mom bought me a Surface Book with 128 GB of storage for my first year of college. I figured that it would be cheaper to get the 128 GB version and just increase the storage via an SD card. Upon inserting an SD card for the first time last week, I was kind of disappointed to discover that half of it hung out of the slot. Not exactly what I'd call useful (for my needs anyway).After some digging, I found the BASEQI. I was hopeful it would be as nice as everyone on here says that it is, and it definitely is! It is machined beautifully, and fits my Surface Book perfectly. It is completely flush with the body of the laptop, and is pretty easy to remove too. The color doesn't quite match 100%, but seriously... who cares?! It looks great and works great too. Thank you so much! A little pricey, but totally worth it. It's top quality, for sure... and even after purchasing this along with an SD card, it's still a heck of a lot cheaper than buying a Surface Book with a higher capacity drive. And not having to deal with a protruding SD card is obviously a huge plus too.

Fantastic! Works well with my Microsoft Surface Book 3! Easy to install just pop in the microSD. Looks great you can’t even tell it’s in. It’s the same color.

Update May 25th, 2017:I interacted with the company support via email when my adapter would not read my brand new Samsung 128 gig card. I could put the card in the shipped SD adapter and my SurfaceBook would read it just fine. They agreed it sounded defective and sent me a replacement, and asked me to send mine back so they could run tests on it. I appreciated that (as I am a professional in the technical field), so I did.The replacement adapter came in what is the inner packaging for the card. Obviously opened. I looked carefully at the outside gold contacts on the adapter and there was a slight blemish you would expect if you plugged it into a card slot. This is what I had hoped would happen. They tested it would work before they sent it to me.So it works. My file copies onto the card are very fast, in the range of about 70 megabytes a second. So the adapter isn't inducing any problems with this card. At this point I am happy with the adapter and will be leaving it in place. I'll be using the space as a backup location for my files / code / documents. A SurfaceBook can die at any time. If you don't have a backup of your data that you can have outside of it, then you just lost the game. Using this with a big enough card as your removable backup will safety net for when that happens.I would not suggest you keep pulling this thing out and swapping cards in it. This was built to be flush to the surface of the SurfaceBook. It is possible to extract the adapter with your finger nail. But each time you do, you add a little more wear and tear on it. So keep that kind of swapping to a minimum if possible and it will last a whole lot longer.Why four stars? The only thing I could ding them on is quality control. One person gets a bad one, you say "well, that was unexpected". But when more start popping up, then you know you have a problem somewhere. With an adapter this simple, that should be so unlikely to happen that when it does, it should also be: "well, that was unexpected".Note that there are absolutely no quality control concerns with the physical device itself. It is well made in that aspect.------------------------I don't normally write reviews this quick, but when it doesn't work - may as well. I have had it in hand for 4 hours now.I bought mine and a new Samsung 128 gig micro SD card for it. Put them together, put it in my Surface Book, and nothing shows up. Which isn't quite true. In Windows 10 device manager, it shows an SD card device connected, but as if there was no 'drive' in it.Take it all out, place the card into the Samsung supplied SD card adapter and into the Surface Book, and it works just fine.Take out another 128gb MicroSD card I have in a Surface Pro, and have been using for months. Nothing. Use a 64gb card I have laying around. Nothing. Put them all in the Samsung adapter - they all work just fine. (all my other cards are SanDisk)So you would think 'well, its dead then'. And here is where it gets weird. If I put a 128 MEGAbyte card in it, then that pops up just fine.So something is going wrong. I'll try and see if the manufacturer will directly interact with me to resolve. Otherwise it is a risky purchase I don't advise yet.If you are looking for an aluminum hole filler to plug that gap, well, then this $25.00 gap filler fits right in and flush too. A bit much for that task though.

Model-350A fits perfectly flush in the Lenovo Legion 7i Gen 10. It fits securely, looks clean, and is great for keeping extra storage installed without affecting portability. I use it with a 1.5TB micro SD card and have no issues.

This is a well-made and clever device that allows you to save some money on the Surface Book 2. I have the 15 inch model and saved a few hundred dollars by going with the 512GB SSD version over the 1TB. Knowing that flush-fitting SD card adapters were available made this work for me. The Base Qi 351A model is made for the 15 inch Surface Book 2. It fits perfectly. It is completely secure, out of the way, and won't snag on anything, yet leaves access to the fingernail groove from the top for ready removal if necessary. I've attempted to capture just how it fits and the fingernail groove in the picture. After installation, the SB2 immediately saw the card, and has done so after shutdowns and restarts as well. The aluminum edge of the device adds some rigidity to the adapter and compliments the finish of the Surface Book but does not exactly match it. The price seems high for something as simple as an SD card adapter, but this is a high quality device and it can allow you to save many times its cost on a high end computer like the Surface Book 2.

I ordered this for the Microsoft Surface 2 15 inch laptop/tablet. No amount of fiddling would allow this to work with my laptop and a known good microSD card. Thinking I might have gotten a dud, I initiated a return and replacement. That adapter also does not work. It's a great idea but something is lacking in the QC department. Hoping to find a similar item.

Cet adaptateur permet d'utiliser une micro SD comme extension du stockage interne, comme ce qui peut être fait sur une Surface Pro !Le design est en adéquation avec le Surface Book et devient invisible, on l'oubli viteJe recommande !

Got struck and doesn't work as expected cannot remove so cannot return!!

Inserito sul Surface Book 2 13.3" con una microSd da 400Gb classe A2 per espandere la memoria; l' adattatore sta perfettamente a filo e la SD è riconosciuta correttamente, senza cambi di performance rispetto a quelle originali.Ottimo prodotto!

ExcelenteQueda perfectamente en mi Book 2 de 15pulgadasCreo que es un accesorio algo caro pero debo de decir que cumple perfectamente y queda completamente escondida así así cuando la guardo la Lap en la mochila no hay riesgo de que se caiga o dañe.

Used in Surface Book 2 and currently holds a 128GB Micro SDHC card. Ideal for its intended use. A full-size SDHC card (or a normal convertor for mirco SDHC) sticks out the side, and I like to have an SD card permanently installed whether at the desk or travelling. This is an ideal, good-looking, solution to the problem. Its slightly overpriced, but I've not marked it down because of this. Why? Because even though it costs a lot it is value-for-money. It is made of metal, looks like an original part of the computer, and allows me greater versatility of storage at a far lower cost then buying a Surface Book with more internal storage.
