Query: a disappointment

After trying other math toys where you had a twist knobs to enter an answer, this toy seemed superior in that you could quickly hit the correct answer with the mallet. Because they've tried to make this more "fun" by only accepting the correct answer when the numbers light up, there is a lot of time sitting there waiting for the numbers, and NOT much time actually drilling math facts. Additionally, I was disappointed because some of the questions are formatted in a more complicated way giving you 7 x ? = 35. This could have been a really terrific speed drill game, but wound up being complicated and frustrating for my kids who are still learning the answers. They can't deal with not only having the correct answer but getting it when it lights up, before the time is out, AND having to hit "enter" after they put their numbers in. ALSO, this game is very big, measuring 8.5" x 15". I will say that it seems to be well made. Don't expect it to replace good old fashioned flashcards.
