Got this kit on 12-2-02, put it together in a about an hour, I swear that it is possessed or something, it has the most erratic movements and attacks me sometimes, I added a switch in the back so I could turn him off easily. It could careless about light sometimes even though its configured to be phototropic, and then other time it is extremely phototropic.
Update 2-06-03: I replaced the CdS Photocells, and now he behaves as he shold, and he is VERY phototropic. I am very pleased with the result.
