This is a high quality product that is holding up well through its first tour of duty with baby #1. Having these sorts of activities in the house that provide stimulation and play are so valuable during poor weather our high UV periods.
Similar, cheaper products are on the market but you get less when you pay less. The walls of this ball pit are flexible without getting damaged or showing really any sign of wear over 9 months of use. This is something I hadn't thought about on purchase but have since witnessed how the cheaper alternatives simply haven't held up over that time period. The flexibility allows my daughter to crawl in and flex the boundary a bit without affecting the general aesthetic once she's done.
There is a slide as well that can be separately purchased. It looks nice and may be a useful addition for others (or ourselves for the second tour of duty!).
Strong recommendation.
