PQI 4GB Intelligent Stick USB Flash Drive i810 Plus. Smallest USB flash drive in the world, waterproof and dust-proof characteristics (Color Blue).

This is the second pqi USB drive I have had. They are tiny and work very well.

I've had this version for maybe 6 months after the first, of the old design, broke (ring and slide mechanism broke). This newer design is much sturdier and I've had no problems so far despite frequently dropping my keys and throwing them onto my desk etc.

If you want a USB stick that is so small you forget about it, this is for you. It won't last forever, but that's because you'll forget it exists and throw it around like you do your keys.

I was looking for a small, simple but cool-looking flash drive, and when I bought it, it was exactly as it's pictured. I haven't had any problems with it and I've been using it since October 2009. I used it mainly for storing word documents and powerpoints etc. for school, and it works fine on both mac and windows. I really like the look of it, and I haven't had any issues with the slider. You can tell it would probably be easy to break, so I keep it in one of those Mini Altoids cans (i ate all the mints and folded up a tissue and let it sit there so it doesn't slide around) and it fits perfectly! And nobody will steal it because they think the Altoids can just has mints in it. Even though it has a keychain thing on it, I wouldn't recommend sticking it on a keychain because it'll probably break.

I have a medical condition and need something to put all info incase I could not speak for myself. This fit the bill.

Thanks
