Ultra Fit USB 3.0: Excessive Heat

same here, i bought 64 GB SanDisk Ultra Dual USB Drive 3.0, i just plugged-in only (both PC and my Android phone), not doing anything, then it gets very hot. Do you solution for this, @dromedary? i am afraid that i bought defect product. Can we get replacement for it? If you have, please share your solution.
