Great but the base could be slightly larger.
Overall this product is great. It inflates uniformly, is easy to use and the weighted ball inside is a nice addition. Being able to remove the pump and have the plug stay inflated is a nice touch as well. It feels like it will be durable and last well.
The main downside of this is the size of the flared base. As you inflate it, it starts to get pulled inside. Given the size it can easily be inflated to, this feels like a bit of an oversight. The pump being able to come out is also a small downside as it comes out easily, and then can be hard to get back in while inserted.
Regardless of the downsides, I would still recommend this toy.
