much bigger then i expected
It's weak and slow, but it's working - you just have to get it out of finger and lay it flat over the reader, and in about 3-5 seconds it reads it. I used it to clone my LaserForce card into it, so while it's annoying, I don't care so much. However I wouldn't recomend it for anything, that require frequent use, for example unlocking doors several times per day...
