A couple years ago I got two on sale and gave them away as gifts. One turned out to have a bad compass and had to be returned. The return process was a little slow, but no problem. The recipients both found them entertaining and spoke well of them. Personally, I don't need all those functions integrated into one card, so I carry a separate knife, Photon II, etc.
If you want a compact, flat knife, I like the Spydercard better.
