## Questions & Answers

**Q: Does anyone know (yet) if this fits the 15 inch Surface book 3 ?**
A: Perfectly fits surface book 2.
Book 3 has identical hardware.

**Q: Will this fit a Surface Book 2 15 inch?**
A: I use mine with  Surface Book 2 13.5” Screen and I cannot see why it wouldn’t work with a 15” Screen. The only reason to buy one of these adapters is so it sits flush with the side of the Surface Book.

**Q: will this fit a normal laptop sd  card slot?**
A: I do not think so. It was custom made for the Microsoft Surface Book. Other Laptops have their slot deeper than the Surface Book. A normal SD woud stick out on a Surface Book, hence the design of the micro SD card in the BaseQI which fits snugly and evenly in the Surface Book.

**Q: Which one will fit the MacBook Pro 14 (2021)?**
A: No, this product cannot fit the Macbook Pro 14 (2021), and our new adapter supporting UHS-II transfer for the 2021 Macbook Pro 14" will be released around end of Q1, 2022.
