I bought this for my 3yr old son over a year ago, and he still plays with it all the time. Our walk-out basement has a big open area we use for playtime when the weather is bad, and this is a nice addition for the downstairs entertainment.
It was very easy to put together, and it comes with one basketall, which is just the right size for little hands. There are two models available: one has adjustable height (with blue column), but this model (with yellow column) is not adjustable.
(We have neighbors who use theirs outside; there is a cap you can take off to fill the bottom with sand, so it doesn't blow over.) This is a favorite among all the little neighborhood kids.
We also have the Little Tikes Totsports Bowling Set, so our son doesn't get cabin fever during snow-ins or rainstorms.
