Review on M8 1 25X25mm Locking Bearing Castors Casters: Efficient Solution for Smooth Mobility by Todd Stovall

I need to move my cart between multiple buildings on different campuses. The original 2" casters on my projector cart get caught on the ADA sidewalk ramp domes. These 4" rubber casters overcame this problem with no problem. I can move with much less frustration. They work smoothly on the floors of the building. The kit came with tools and bits that I didn't need, but having them included undoubtedly saves time when I need them. 5 stars for good quality at a reasonable price.
