Review on Heavy Duty Furniture Leveling Feet for Enhanced Stability: Anwenk Adjustable Table Leg Leveler with Lock Nuts - Perfect for Furniture, Tables, Cabinets, Workbenches, Shelving Units, and More by David Dreher

Controllers look good, but hardware is cheap! get your own Most of the included screws either broke off or fell off easily. They don't give you any extras at all. Any that broke broke inside the tree when I screwed them in. This caused a big problem because now I either have to find a way to get them out of the tree (which is hard to do without ruining the tree or screwing up the controller). Another option is to change the position a bit, which I did, but then another screw broke. Before I knew it I had 3 broken screws in the same piece of wood. So I had to use mine. One or two do this, I would say user error. But after 2 or 3 bolts broke from EACH regulator it couldn't be me. Bought 4 of these sets. Of the 64 screws in the kit, 33 broke and another 12 fell off.
