These wheels are awesome. I bought them and put them on my chair. The chair is now lifted a little bit, which is not bad for me. But the best part is that it is very smooth now and the wheels are very quite and don't produce any marks on my floor. I certainly recommend this product to anyone who is looking for wheels for their chair or some type of outdoor product. It's good for both, outdoor and indoor products. #PenTrean1

I received this product free of charge in exchange for my review.
