We bought this ball pit for our nearly 1 yr old son and absolutely loved it. It can be super fast & easy to build and in terms of quality, it also makes a very good impression. The set includes already 200 balls included, but we have the same again already ordered when purchasing 600 balls to. Thus, it is now really a great ball pool, as you yourself still knows it from earlier ;-) The balls also make a good impression and all have beautiful bright colors. I find it very good that they are not too hard, so give quasi, but sturdy enough to sometimes vigorous romp or "biting attacks" our son withstand: D
So overall we are really very happy and can it to anyone who is looking for a beautiful ball pit, only recommend! :)
