We have had great luck with these reels. I have a small wood shop so most things have to be moved on casters and these casters are just right for an unfinished floor. Just use 2x4 and attach these videos and you have a mobile shop. They appear to be completely maintenance free, just blow off the sawdust and some WD-40 and they're good as new. I've tried polyurethane rubber coated rollers and while they are smoother they just deteriorate in the heat.
