Used several times in different sizes on Cruzer Fit and Ultra Fit. All did well. They do get a little warm when in use, but so far that hasn't been a problem. The small size is very useful for many applications (car stereo, extra laptop storage, etc.). I solved the SMALL WIRE HOLES PROBLEM on the Cruzer Fit. a craft shop named after an archangel and beginning with an M. A 6mm split ring fits into the tiny lanyard hole on the Cruzer Fit and then provides enough room to attach any lanyard or keychain to the split ring. on a small flash drive and protect against loss. I loaded audio Bibles onto these CDs to give away to friends and now I have enough split rings to last a long, long time. See photo.
