I’m having trouble with one of my three units. Two have been rock solid since I installed them A year ago. One, however, keeps drifting up and pointing above the door itself. I’ve realigned it several times, tightening and loosening the screw to varying degrees and it always drifts up again. I’ve removed and replaced the 3M double sided sticky tape, and that didn’t make a difference. I’ve pointed it lower to begin with and used 3 reflecting pads to increase the surface area. But it still drifts back up and settles in the same position above the door. I suspect the mounting clip may be damaged or worn in such a way as to make it slip back to that position over time.
I’m now considering getting it to my desired alignment and then gluing the damn clip into position. Any other suggestions? Is there a way to order a replacement mounting clip to see if that would help?
