The toenail paint on any of mine has rarely lasted the first week! The newer RB paint does seem to last longer, but the rubber on the feet takes a lot of rubbing from the Pleo's movement and on the Ugobe Pleos it does rub off fairly quickly I'm afraid. The little holes either side of the camera on Pleo's nose are the IR transmitter and receiver, so one transmits and one receives and you will only see one flashing (in videos mainly). The edge detection needs good light, and also will not always work if the Pleo is at too much of an angle to the edge, so don't rely on it to keep him safe! He's lovely and he sounds fine, enjoy him!
