For the cost I wasn’t expecting a lot but figured it would work for my needs. Bought 2 sets for our ATVs to move them around in the shop. Work excellent for a 900lb. ATV. I might be a little hesitant to use on a 3000lb + vehicle as they don’t seem very heavy duty but otherwise all parts seem decent. Would compare them to the inexpensive Harbor Freight wheel dollies but better price.
