Review on POWERTEC 17050 Swivel Industrial Caster by Wayne Ohlrogge

I expected them to be junk but they are really awesome. I can pick a few things, but it doesn't really change how well they work. I used 4 of these on a 5-600 lb weld cart. Far from the right rating, but the cart moves easily. Buttercups are pretty stupid. The only way I see them working is to spin the reel fairly quickly while pumping the lube. They're colored, so if you're going to weld them, you'll need some preparation.
