The castors themselves are very durable and exactly what i wanted. The sturdiness and smooth flow as they swivel is impressive. Tuve que comprar otros tornillos with sus tuercas.

These wheels are great at a good price. They roll very smoothly. Wheel lock is easy to use and works great. Wheels are super slick. Comes with bolts.

The replacement order were damaged and clearly previously used. The picture and description indicate that the wheel itself is a 4 inch diameter but what i received has a 3 inch diameter wheel.

If your floor is not perfectly flat the casters become unloaded when one rolls over a dip in the floor. The springs keep the lift arms from disengaging.

I feel like amazon is starting to get sloppy with this stuff. Not happy at all.
