Review on Aozel Threaded American Locking Casters by Thomas Unruh

Unlike the last three pairs (various brands) I've bought these are holding up very well. I put them on my 700 lb four wheeler and unlike the last three sets they work very well. It was also the only pair that came pre-lubed. I bought a 4" kit. After a week of use, one of the rollers broke the stem completely in half, breaking the 1/4" threshold. With only 200 pounds on it.
