I bought one of these purely so that I could install the netbook edition of Ubuntu onto my Asus Eee, and it worked a treat; after following some handy instructions on the internet I turned it into a boot drive and installed Ubuntu onto the Eee's flash drive and it worked and then I was happy and no-one died. The stick has since come in handy as a quick way of copying data from my laptop to the main computer, and does all the things that ye olde floppy disks did when the world were young.
On the positive side it's capacious, tiny, feels fairly sturdy, weighs nothing, would probably float in water if it was airtight. Creaks a bit when I squeeze it. There's no cover for the USB port, and the thing that looks like a bright LED in Amazon's image is actually a hole for a keychain. As the other reviews point out, there's no status light, so you just have to be careful not to pull it out prematurely, fnar. My advice is to just ram it in there, good and tight, and give it time. Don't force it. Don't get nervous, there's no rush. Take a break if you feel like it. Make sure the data's transferring alright; give the computer a kiss, compliment its fan noise or something.
It's ergonomically designed in such a way that it's easy to put into a solo USB socket, but tricky to get in and out of a socket that has something else above it. But I'm splitting hairs here.
