Review on 🚀 Rocky Mountain Goods Filled Wheelbarrow by David Bowens

I bought this because AMAZON's description said it would fit a 6 cu ft wheelbarrow well but when it arrived the attached one gave printed literature has a maximum weight limit of 290 pounds. If one cubic foot of concrete equals 150 pounds, then this suction cup can't even support two cubic feet of concrete when mounted on a 6 cubic foot wheelbarrow! deep as the pictures show, but the hub is 6" tested and the bearing is 5/8" tested. 500 pounds or 3 cubic feet of concrete (450 pounds)!
