Came broken and missing pieces but the company was quick to send new foot pads and the missing pieces. Once the company sent correction it was still not possible to put it together as the bolts were not long enough to screw in and there were no instructions. There are two spaces for bolts to hold the leg piece on, the top opening has a drill out to let the bolt pass through and screw in fully, the one below does not, making the bolt too short to touch the body of the equipment.
