It grips well to the ground and as some said and the tilting of the platform can be a bit too easy to happen, but it's just a matter of getting used to it. By now I actually consider it a feature. Dirt from your shoes can easily get trapped in between the ridges at the top, but being hard plastic, it's very easy to vacuum it, especially with a brush tip if you have one.

Great product!

Très confortable!

Je ne l’ai pas garder parce que je n’ai pas l’espace suffisant mais ça aurait été vraiment bien!

It wasn't exactly what I thought it was. I assumed it was a spring to apply pressure. It simply adjusts position. But, it is well constructed and works.

simple and works well. This is my repeat order.
