The stick is excellent. The rotary cap is quite windy, but I'll probably lose weight anyway. The rest is top. The card fits tightly inside, the lid closes tightly enough (other customers he report was too loose, I find the totally OK). The device provides with a UHS-I card (SanDisk SDSDXN-032G-FFP) excellent transfer speeds (51Mbit when transferring a large 8 GB install.wim for Windows). I am very happy with my new Windows installation device.
