Review on Educational Insights Math Slam: Fun Electronic Math Game for Children, Ages 5+, Enhancing Addition & Subtraction Skills for Home or Classroom Learning by Donald Gore

The game itself is wonderful. The kids love it so I give it 5 stars. Be careful though - this toy arrived used. Twice. We received these for Christmas and it is clear that the box had previously been opened and sealed with tape. We decided to keep it anyway until we realized the toy itself was broken. It would suddenly stop working mid-game or wouldn't turn on at all even with fresh batteries. We returned it. The kids asked if we could buy again, which I did, thinking the chances of us buying a used toy twice were pretty slim. The seller was Revain, not a third party which I mistakenly thought to be more reliable. Well it just arrived and there's a good chance it's the same one I returned, now with even more scotch that was closed. It's coming back and we won't be buying from Revain a third time. Time to go to the good old toy store!
