They work well on my bamboo floors and I am zooming round my office with ease.
These casters are way better than the ones that came with my office chair. They roll easily over my tile floor and are much quieter and smoother. I gave them four stars because I've only been using them for a short time, so I can't comment on durability However, they seem very well made.
Straight out of the box, there are 5 pairs of wheels. Of the 10 total wheels, only 1 spin freely. Of the remaining 9 wheel, 4 had moderate drag (could rotate maybe 1/4 around in a single flick), and 5 had significant drag (less than 1/8 travel in a flick). To compare, the original plastic wheels I took off spin like tops, even the one where I could hear plastic-on-plastic rubbing. Figuring maybe there is a difference if installed, I swapped these in. Getting my chair around became more difficult than it already was. Note, this is on low pile carpet, one step above office carpet. Up until recently, I was rolling around in a 15th hand early 80s office chair, and it went around the same area with only minor issues. I have a second one still, so used it to check my memory in these tests.Just to be sure, I took the chair out on the hardwood floors. Well, the noise from the wheels is now more bass than treble, but the overall amount is no different. 100% not silent as claimed. The movement is better, but it's still sluggish. Oh yeah, and one of the bear caps fell out. That gave me an opportunity to look more closely at the setup, which helped explain the problem. The bearing shaft can move side to side, pinching the wheels and causing drag.Long story short, not a fan. In theory, these are rubber wheels, which I'll give them one star for, but they might as well be hard plastic for the amount of give in them. On hard floors, they're passable but not what I'd consider good. On carpet or rugs, don't let the advertising claims fool you.I'll be switching back to my original wheel set now.5 stars - Excellent/Perfect - This is the stuff right here, folks!
