This was great when we first got it. I was excited about the solar to power instead of lots of batteries. However, 4 months later, it's not working at all. The drawer opens but the display is dead. I've changed the small watch battery and even set it outside in the sun for a few hours thinking that maybe the light in the house wasn't strong enough. Nope. Maybe mine was a defective unit but it certainly wasn't abused or even played with to an exceptionally high degree in the 4 months that we had it.
