Extremely small, relatively fast and super compatibility! The stick is a perfect solution for those who want to go quickly larger files have with them. Or for precautionary people who make a CWM / TRWP backup right at the stick! With 32GB one has quite a bit of memory. The USB3 interface supplied with my hobby try to 80-120MB / s, the phone there are 20-30 (of course, since there is only one USB port is 2.) You should make sure that the phone actually has USB OTG! (When Nexus 4, this is not the case) I would recommend this product to all those who need more space or on multiple computers and, moreover, a tablet / phone work and its files must always have with you!
