My son received this as a Christmas gift. It is somewhat tricky to set up (it took me a while to get the green ramps/chutes to stick properly, but trust me - they do if you persevere) and you may find yourself tripping over the big feet and little balls that inevitably end up in the middle of the living room, but it is great fun and a very entertaining way of teaching your child numbers and colours whilst helping develop their dexterity.
It is quite big (I can contort myself to fit inside, and I'm hardly petite) but sturdy enough for a child to pull up on without everything crashing down on top of them.
It's not the sort of thing I'd have bought my son, but I have no problem recommending it. It is harmless fun that will last a good while.
