Love those rollerblade wheels for anything on wheels, they roll smoothly, silently and are gentle to the wood floor. They also raise le base level of my chair which I like. The break is the reason why I can't put 5 stars... Completely useless, i was hoping to use it because often I want te chair to stay in place and it roll really easily with those wheel... Well since that brake can't be locked in place it's useless. I do recommand the break-less version if they are the same price!

I thought the brakes would be useful but they just get in the way. You could.. modify them but maybe just get the other ones without brakes.

It can stop the chair from moving, but when you want to move the chair you have to apply more energy.

Just received. Installed but productb must be tested for at least six months for a fairv review.

bonne qualite roulement souple j'adore

The wheels arrived in good condition. They roll smoothly and the brakes keep the chair stationary. There is a slight pause when changing directions as the wheels have to turn before proceeding in the new direction which will need time getting used to if you are using the typical casters that come with the chair... however, these should be much more durable and avoid catching hair and carpet.
