Pros: Works right away. Great storage capacity for the price. Used this to back up my music collection, some photos, and word files. USB 3.0 makes short work of transferring my ~50 gigs of music.
Cons: While I like the slide idea to protect the business end of this drive, I personally prefer full covers or caps for my thumb drives as it keeps debris/gunk from getting in there, but I don't plan on keeping this one in my pocket/backpack daily. Just something to consider.
Summary: I cannot replace it due to the 30 day replacement warranty, so that's $15 out of my pocket which I don't have the money to replace at the moment, and it was being used for schooling. Not fun when all of your important school documents get corrupted and the thumbdrive is no longer accessible anymore.
Pros: It's a very quick and good thumbdrive, with fast write speeds.
Cons: I've had this only about a month and a half and I just found out that the whole thumbdrive is useless now due to a I/O Error, when I've taken very very good care of it during the time that I had it. It has not been dropped, misused, or anything... I'm very unhappy with this.
Summary: Love it, I don't usually care much for read / write speeds, but I figured a USB 3.0 storage device would come in handy. I got this one 'cause it is 128 GB of 3.0 goodness for $60 (or thereabouts). Very happy with it. You'll never lose the USB if you're someone like me, because you know what it's worth and no-one else has a USB that looks as unique and awesome as this one. Enjoy those lightning fast transfers too!
