Review on Ravinte 60 Pack Soft Close Hinges for Kitchen Cabinets - 1/2 inch Overlay, Satin Nickel, Stainless Steel Concealed Hinges, Self Closing - 30 Pairs by David Baer

Most hinges have an oval screw hole that attaches the hinge to the front frame. To adjust the door up or down, loosen these screws, move the door to the desired height, and retighten. These hinges use an inferior system in my opinion where the mounting hole is basically round so there is no adjustment possible. They are essentially mounted in a fixed position, then there is a screw to move the hinged movement up and down. The problem is that the setting is probably a little over 1/16th of an inch. Not enough. And if you drop a loop, the other loops obviously don't adjust, so they just hang on until you can adjust them too. If I'm not missing anything, this seems like a really bad way to go, and would mean I would have to drill lots of new holes about 1/4" from my existing holes to line up my doors.
