I have brought many pendrives and none of them had failed me. All the times the pendrive producing only less heat so you can use this drive for a long time. Some pendrive offers you a lifetime warranty but that does not mean that the service centre in your state. You have to send the pendrive to foreign countries to make a replacement.
But no worries you can count on this pen drive. The White coloured version of this is very good and transfer the files very fast.
All the products from transcend is very good except the memory cards.
