This key has the advantage of an attached hood, which turns away when you use it, and protects the USB plug the remaining time. There is a small loop for attachment to a wrist strap, if necessary. The outer shell is sturdy black plastic swivel cover is glossy black with the name aLLreLi, printed in white. I find the design quite stylish and attractive.
This key has a USB 3.0 connector (blue band), which is fully backward compatible with USB 2.0 ports and, when combined with a 3.0 port, produces exceptional performance. With my old PC running Vista and a USB 2.0 port, I timed transfer speeds of 18-22Mo / s with audio and video files, four times faster than my other USB drives. On my new laptop with Windows 8.1, transfer speeds were around 42 MB / s, peaking at 52MB / s, which I find impressive. I got a free sample to evaluate it, and I can honestly say I am really happy with his performance and large capacity it offers, so I can recommend it highly.
