Yeah, my doors flop open all the time. My magnet seems nearly dead and at first I didn't understand you had to attach the magnet part to the light saber hilt. It looked like they were just using the end of the light saber as it came in the directions. The door where the light saber goes wont really open on mine so I am afraid to stick the thing in there and not be able to get it back out and the extended parts of the two of the arms are really loose and just slide up and down on their rails in the body. I see a lot of potential breakage or at least wearing out of parts if they get used too much.
Overall I am really happy with him anyway, I am not sure if there is a trick to the lights though, mine just keeps cycling through colors, I thought there was different modes but the directions really didn't explain anything. Am I missing something with this?
As for sales, not sure. At SDCC Sideshow was selling him for $149 with tax included and lots of people ended up buying them from the booth. They had 50 custom R2's for the R2-Me2 display and that brought a lot of attention at the booth.
