These castors are extremely smooth rolling. I had tried a different set of rollerblade style castors but they didn’t have ball bearings around the wheel axle and you can really notice the difference between these which do have bearings. These glide effortlessly across my wood floors and the soft rubber is good for preventing scratches.
Installation was easy and I had no issues. The build quality is very nice on these.
Full Disclosure: I received these at a very high discount in exchange for my honest review.
