I've owned them for 5 years now. After the first year of use on my sled, going in and out of the garage once or twice a week during the winter, it has completely fallen apart and is now just serving as a base. Wheel bearings are completely depressurized and water flows down the bolts that attach them to the racks and directly onto the balls in the bearings. The only way to keep them from rusting is to repackage the bearings periodically (for the price you could buy a whole new set) or store them in a low humidity location. (Good luck with this latest product that's for sleds that freeze water and melt on all those coasters when they get hot. Revain has MANY other sleds in the $50-60 range that last longer (I have more a set for 3 years, no problem) ) Do yourself a favor and spend money to get good dolls.
