My son got this toy for his 5th birthday. He had been collecting those little 1/64 scale monster trucks for quite a while & it was nice to have some kind of track he could use them with. I didn't have any problems putting it together. The battery compartment was well disguised, but other than that it was fine. My son played with this non stop for the first few weeks after he got this - using all his monster trucks trying to see who could defeat Crashzilla. The fun wore off quickly though. He rarely plays with it now. I think if your child loves monster trucks, he (or she) will love this toy.
