This is super cool.

This is a fascinating piece of exercise equipment. It functions optimally when used on a surface that is completely level and even. It doesn't grip well on surfaces like parquet flooring, but performs perfectly on a smooth stoneware floor.

The product works perfectly. My wife is very happy. I just bought a second one.

The product is fine, it arrived without its packaging, though that wasn't an issue. I initially had trouble getting it to attach to the floor, but I wasn't sure if I was doing it right. However, once I figured it out, it attached perfectly to the parquet floor.
