Super Quick delivery (Next day). Great wheels. This is the 3rd set I buy. I had a set on my chair and my son's chair which I bought a while back. Daughter recently replaced her chair, and decided to get her a set also. Way better than any stock casters. They work great on hard floors, and even on carpet (not on 80s style long shag carpet however) :) As soon as I got them, I decided to spray some JIG-A-LOO, Dry Film, Garage Door Lubricant (Blue can - available at most hardware stores), into the wheel bearings (from both sides) and the swivel bearings (base of the top post). Makes a huge difference to minimize friction. Take a wheel, and try to spin it. Spins nicely, but after 2 or 3 turns it stops (normal). Spray the wheel bearing on one side and spin it, and then turn it to other side, spray and turn it to get it to penetrate. Then perform the same spin test as done initially, and the wheel just keeps on spinning, like it doesn;t want to stop (at least 8 to 10 revolutions). Minimize friction should also increase the lifespan of the bearings. A1. These are a must for office chairs.

Replaced the casters that came with the DPS gaming chair from Costco with these. It's a lot quieter and feels smoother when rolling around. A couple of cons for me: 1) it adds about an inch more to seat height, making it a little awkward to move around (I'm 5'7" and the seat is already at it's lowest). It also means my chair can't tuck under the desk anymore. 2) there's a bit more resistance when try to roll in one direction and then another. I fear the constant rolling around will wear out the rubber and end up creating a flat spot. but only time will tell.

Excellant

Fonctionnent parfaitement!

Great product, good price.

Best price for these rollerblade style casters. I've swapped all the office chairs in my house with these.
