I went to Sears last night to check it out. I was quite disappointed with the quality, in particular the casters. The swivel part of the casters all binded such that you could position it wherever you wanted and it would stay there. When I tried rolling it around the floor, the casters would not always change in the direction you were moving, the wheels would drag instead of roll. I looked at a different creeper that has the bent frame for your shoulder (Model 51158). The casters are red in color and were much better. The swivel part rotated smoothly and freely. The wheels are also a little larger and wider. Of course, this model cost twice that of the non-sale price of the other, but I guess there's a reason for the bundle packages and the 50% off sales. For $15, you get what you pay for, but I certainly wouldn't pay the full $30 price.
