Review on Side Mount Heavy Duty Steel Furniture Leg Leveling Feet: Adjustable Height with Round Foot for Desks, Tables, Shelving Units, Shop Cabinets, and Furniture - Set of 4 by Leon Johnsson

Not very happy now. I finally installed them today as I'm just about halfway through assembling my workbench. I dropped 2 out of 4 to start leveling the table. At this point, the two black supports (plastic only) have fallen off the stem, allowing you to lower and raise your leg with an Allen wrench. I'm collecting the pieces back, but they keep falling off. This is so unacceptable. I originally wanted to buy their Rockler version but they were cheaper. now i know why Compared to Rockler, the only visual difference I see is that the Rok version has a metal base for the part that touches the ground, with a black plastic cover/rubber pad surrounding the metal part. However, these levelers are useless to me as they are. I shouldn't be looking for a way to get her to stay together. I have already submitted a review and am waiting to see what they will do, if anything. photos attached. There is a Phillips screw on the underside of the black plastic stand, but the other end of the so-called screw is unthreaded. Instead, they're vertical strips of metal with little indentations, I guess you can call it that. The unthreaded screw simply slides back into the metal bar, causing the foot to rise and fall.
