too small, no key ring hole, no dust cover, very easy to lose.

I'm feeling disagreeable today.

Small is good. It has a key ring hole. Dust cover unimportant except in sand storms. I might not care if I lost it because it's very slow as are most Sandisk flash drives.

They also seem to have totally ignored USB specs by making the USB connector plastic instead of metal which was supposed to connect the electronics to ground before data lines to lessen chance of ESD damage when plugging it in. At least it seems to have power and ground pins about 1mm closer to the tip in an effort to offset this design quirk.

I got the 8GB version and like its small form factor. no problem with dust or heat. sandisk brand is reliable.
