I will say that I am surprised that such a well built product is being manufactured in the U.S.!  I figured with all the tax breaks to outsource everything, companies would be foolish to do that...but I am glad to see that DAE is not worried about those types of things!  They appear to be more focused on building a relatively nice creeper!  This thing is comfortable, sturdy, easy to maneuver, and can roll over just about anything!  Required minor installation of the casters, but that became an activity that my four year old could do!
