Rated for 3+ but my 2 and 3 yr. olds both play with this. While the kids like playing with this, I like that it can grow with them. It has basic tools for younger children: rolling pin, presser with three tips, pizza cutter, safety scissors, play-doh knife. But it also has tools/items for older ones: bead making, art molds for pictures and "sand".The only con is the mat. It's cheap plastic. Sounded great on the box in the store, but ends up crinkled underneath them and not protecting the floor. Stick with using and old sheet or vinyl table cloth from the $1 store.
Positive

This thing is a major piece of junk. It doesn't stick to the wall like it claims. You have to stand to play with it (cause all the cool stuff is at the top), and the extension pieces constantly fall off. I actually screwed it to the wall, but that lasted a whole 10 minutes as it wouldn't stay screwed into the wall. Then the scenery kept falling. Save your money and buy the cool batmobile or something.
Negative

No doubt the worst of the many attempts to cop the ideas and success of Bill James, Pete Palmer, etc. over the past decade. Cute names and sophomoric humor aside, there isn't a great deal of meaningful analysis here, and if you take the time to go back and look at the previous year's addition, you will see that these guys are wrong a lot more often than they are correct. Their arcane formulas and measurements totally miss the point of something as simple and palatable as Runs Created, and the result is a dull and confusing mass of EqA's.

Negative
