It seems odd that Duracell (which we all think "batteries" when we hear the word) has made a flash drive. Being the techie that I am, this flash drive hasn't failed me yet! I use it for movies, my xbox 360, music, pictures, files etc.. I have reformatted it LOTS of times and reused it LOTS of times. I bought it at an inexpensive price (figured it would be CHEAP because it WAS so inexpensive), but my expensive one (not Duracell brand) failed and this one is still going strong!
