Well I read many reviews of this product from other suppliers and many of them were not favorable - numerous issues. Mine came with a plastic broken small support leg that screws in right by the hinge to take weight off the hinge but I had a small hard rubber bumper to replace it rather than send it back for this small annoyance. I would suggest to future buyers to keep the shipping packaging for at least a few months before recycling the cardboard. The shelves  that fit standard aluminum cans are a little close together making it hard to get cans out. This unit gives off a lot of heat so make sure you have adequate ventilation if installed inside a cabinet. I purchased a small fan to help circulate the hot air away from the unit. Unit is working now so time will tell.
