Purchased one set of brackets and it held up a 1/2 piece of wood as a shelf, plus the silverware i put it in. I purchased 3 more sets of brackets. One of those sets of brackets was made into a 30in wide shelf, has 3 strong magnets and my cuttlery on it. It stays in a stowed position just fine.the second set of brackets i put with a 1/2 wood shelf about 24 wide. It has 20 spice bottles in it. Not nearly as heavy as the silverware drawer or drop-down knife shelf. It will not stay in a stowed position. It drops down over 1/2in every time you push it up and easily drops out of position on the slightest touch.I've contacted seller and asked if there was anything we could do to adjust the bracket to lock in more. They said the shelf is, specifically designed as a pull down rack hinge made for such things like cookbooks. It is designed to tilt down with any weight put on it at all. They could not offer any fix to the drawer not staying in a full-up stowed position.In the stowed position, the bracket is only held up with two small plastic dimples on each side. I've tried manipulating the bracket so there is more force onto those dimples but that doesn't work.I would say the hinges work well for a shelf no more than 12 wide. Be most importantly be cautious of the weight if you put a front facia piece on it. I had front facia pieces stained to match my cabinets. it was 3/4in white maple. The front weight is what is making it fall down.
