Review on SUNSHINE MALL Inflatable Hamster Knocker Outdoor Sports & Outdoor Play by Eric Aulia

I bought this for my grandson's birthday. When I opened the box, I was surprised that there were no instructions, warnings, care instructions, or even company contact information. Although the concept is fairly simple (blowing air into each section), we had an issue with one-way valves. They don't work like air mattresses, floats, etc., where you squeeze the bottom part of the valve when you blow air in and release it when you stop. These valves seem to make it difficult for the compression to let air in, and trying to just blow them out doesn't work either. We end up opening the valve all the way, inflating the section, and then desperately trying to close it without losing all the air. The result is a slightly sagging ball. Works but disappointing. A little manufacturer advertising about valves would probably help. I cannot recommend them. I also learned a lesson about buying things that haven't been verified yet.
