I have bought this pendrive one month ago from amazon. I already had a 8gb pendrive but now my need had grown also I needed fast transfer speed so I went for USB 3.0. I am very happy with the transfer speed its avg is 25 mbps copying from pc to pendrive with maximum speed of 60 mbps. But while copying from pendrive to pc its even higher its avg is 50mbps and max is 110mbps. It has 5 years warranty.
Since I had not faced any problem I cannot comment about services but the product id good.It is auto detectable no drivers needed.Its compatible with all the windows versions.I am very happy with the transfer speed but the only problem I faced is the heating of pendrive but its fine.For the person who prefer speed this pendrive is for them grab it and experience the speed.
