## Questions & Answers

**Q: Any plans to make one that supports ush-ii?**
A: I am also looking for support of UHS-II - which would make this much faster. Just to let you know, I am going to shop around for a similar device that does that first before buying this. It is important to me to be able to take advantage of the faster speeds of UHS-II or UHS-2.  Thanks for considering it - although it appears you have been considering it since 2016 and it is now 2019 so that doesn't look good.

**Q: Does  this adapter support uhs-i?**
A: If you put a uhs 2 card into this adapter, will it work? I know it doesn't have the extra pins, but will it work?

**Q: The 350a appears to be short ~0.5mm short for the microsoft surface book 2, any plans to support this product?**
A: I emailed the company and they replied that they are working on a Surface Book 2 version, but did not give any details on when it would be released.

**Q: Does anyone know if this adapter fits flush with the new Surface Book 2 model (i.e. does it "stick out" at all?)**
A: For surface book & surface book 2 13.5" - please choose model 350A. 
For surface book 2 15" - please choose model 351A. 
Thanks.
