CONCLUSION:
+: USB 3.0: Very good key. It outperforms the majority of current USB 3.0 drives, for a very reasonable price (especially 32Gb).
+: Recognized by my PC on both types of connections.
- USB 2.0 stick with "ordinary" performance. It could logically expect ...
+/-: The key is pretty with its appearance ("fake") carbon, but the "all plastic" seems a bit fragile (we will see in time ...). I said that the key (such as 3/4 USB3 key) is one centimeter longer than the average USB2 key of the same capacity. Once placed in a pants pocket, it is more exposed to breakage! But OK ...
Added on 12.26.2013: the key has not declined in perf and mechanical strength is very good. So I spend the 5 stars without reservation !!!
I advise because at this price, I have not found better and is really fast USB 3. (useless for exclusive use USB2)
Excelling product (after 6 months of use).
