This machine does a decent job of cleaning when it works, but it breaks way to easily for the price, and its not built well enough to justify fixing. Too many cheap plastic parts. Consider it to be disposable if you buy it.
Negative

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

Loved this from the moment I put it on the bike. Took a little work, just a little, but switched it to my wife's bike and then back to mine. Some where in there we loaded it down too much and one of the slide in plastic brace ears broke and now it is unusable. Searching for a new way to haul groceries now...
