Yesterday, I purchased and installed three of these contacts, and to say I was overall impressed with the fit and functi

on. I had to purchase an 11/16″ drill bit, and the only bit I could find at Home Depot was the flat blade wood bits. I was a little nervous about using these as they are more difficult to keep straight and level.
The install was fast and easy, and the instructions were complete. The fit was very tight, I had to use a hammer and a flat chisel to pound the transmitter case into the door. I was cautious and removed the circuit board and battery prior to installation, to be sure no vibration damage occurred. I was also impressed that it came with both white and brown finishes, as one door was brown and it blended in nicely.

Enrolling the transmitter was easy and quick. Great job to HAI on this product.
