I don't think anyone has posted actual pictures of the baseQi. I've got two for our two surface books. They are awesome. I combined them with a lexar 633x 128GB microsd when it was on sale on amazon for $40. I shipped both the BaseQi and the Lexar 128Gb MicroSD to canada and they both arrived quite quickly.
I bought the iSDA 350A "Ninja Stealth Drive" for surface book from the BaseQi website
I also bought a Lexar 633x 128GB MicroSD card from amazon. I'd suggest if you can afford it get a sandisk extreme or maybe the 1000x version due to random write benches below (Quite bad - see crystaldisk benchmarks below)
Here are some pics and benchmarks of the BaseQi, Surface book and Lexar. All benchmarks are done with a Core i7 512GB + GPU surface book model, with exFAT 1024Kb allocation formatting on the MicroSD card.

Benchmarks of the BaseQi + Lexar (exFat 1024Kb allocation size) + Surface book (Core i7 512GB w GPU). First 1GiB
then 50MiB....
Lastly, the Lexar in it's home USB3.0 Key adapter in the USB 3.0 slot on the surface book at 50MiB. This is to see if the BaseQi or the surface book SD slot adds (or subtracts!) any disk write/read speeds because of it's middle man status as compared to the stock USB key dongle from Lexar. Unfortunately I have no way to separate out the difference in ports used on the Surface book so take it for what it's worth - it could simply be that the USB port on the Surface book is faster than the SD card slot on the surface book.
All in all the performance is not that bad, and I'm happy with my purchase! Highly reccomend the Base Qi!
