Bought this for my 4 year old son, very much against his mums wishes id add :-)
The kit is excellent, very professional and a good size. My son is probably the same size and build as a 6 year old, so the kit takes a bit of a battering, but it stands up to everything and is in same good state as when first bought. My 1 year old (18 mnths) also gets in on the act and is very competent, sometimes they both use it at the same time even! It was well packaged, even double boxed to protect it further, and easy to put together.
i would definately recommend this set to anyone, i wasnt quite sure what to expect but it has exceded my best hopes!
