I’m bought this pen drive 5 months ago of 16GB storage in black and red colour at high price.so, I share my experience about pen drive.First that the material used in this pen drive is so cheaper and it brakes if the little pressure is applied and also the pen drive work slowly.the tranfer speed of this device is very embarrassing.the replacement is service is not prvided in this device. so, please don’t waste money on buying this pen drive.
