Smooth rolling and easy to install would recommend.

These wheels are advancing the chair they are installed on in a great way. They roll easily, are completely silent and definitely protect your floors. They do have one small fault, they develop flat spots over time. After sitting on the chair for a few hours you can feel that these wheels developped a flat spot. On a side note they roll so easy that my chair now goes on trips following my unlevel floor!

Easier rolling and doesn't scar the flooring

belle qualité, ne devrait pas briser le plancher, ça modifie un peu le type de roulement et de déplacement de la chaise

Lets your chair roll smoothly. One thing I found was this type of roller causes your chair to shift a bit when you go to sit back into your chair. It's a bit frustrating if you're coming from a conventional set of wheels where you're locked into place.

Good price to value
