Biggest disappointment in a toy i have ever seen. First of the quality of this thing is atrocious.  The solar powered calculator is really weak, you need a good lighted room for the calculator to work.  Another flaw especially your place is a bit on the darker side. The plastic is such horrible quality that its not even close to be worth the price they are selling this for... it should be 5 bucks at most, not even.  Rip off quality at a rip off price.  Such a huge waste of a purchase.
