Nothing special, but for the price the pump is probably perfect. The grip is not ideal (likely the price for the small size), but if I need to inflate something a few times a year and don’t want to use a car compressor, it’s acceptable. For its small size, the pump has a surprisingly large air volume.
The information in the included leaflet is insufficient and misleading, but the pool itself is very good. For a small child, or in my case a dog, it’s sufficient. It includes one patch; you can inflate it by mouth, but a pump is recommended. Fits perfectly on a balcony so even the dog can cool off in the heat.
Our puppy doesn’t use it for toileting at all, probably because the material isn’t pleasant. Instead, it prefers to relieve itself on a baby changing mat, which is likely softer and nicer.
