More problematic as it is, probably due to its size, is not recognized by all devices (printers, radio, TV, but also from a Win7 laptop, in which the key has been detected as being defective).
For that I have twice received a rather nasty shock when I him on TV and BluRay - wanted to run player. Whether because PNY or manufacturers of other devices have sloppy, I do not know, but it would definitely have been Panys task to isolate the stick for all cases properly.
I'll keep him in spite of everything, the stick can only recommend but limited because of its yet serious errors.
