Purchased this for my daughter's 4th birthday, and both her and my 6 year old have had lots of fun playing with it. The base holds all the extras, which is a great design; however we've now filled ours with sand to keep it upright. The ball is of a firm sponge variety (instead of tennis ball)which is a safer option for the younger age range. The net is a particularly good extra, as it's surprisingly large and so fab for throwing and catching games. The poles don't feel particularly strong, but seem to be standing up to their play so far! (have told the children not to lean/pull too hard on them though.) Have also taken it camping as it's easily collapsed and put together.
In all, a great first Swing Ball with well thougt out extras.
