Summary: This thing is really cool but when I unscrew it it sqeeks like nails on a chalkboard, also, just because your finger fits in it doesn't mean you should put your finger in it; I had the cap sitting beside me while I was backing up my PS3 to USB and because I could I stuck my pinkie in the cap, I was worried that I would never get it out
Summary: great flash drive for heavy usage, just not on a key ring. The design is somewhat backward for use on a key ring. But great design for use in factory, or industrial settings. Waterproof, dust proof and as strong as a Maglight.
Summary: Had a USB2 version of this, which I lost, so this is a sweet replacement - USB3 will give it some serious lasting power. Now I have to manage to hold on to it - and the cap, without which it's just another flash drive.
