Programmed fine for my security gate. But, the range is very short, and once inside, seems even shorter (I assume the transmitter is right in that unit, thus its shorter range from the rear).

I have to pull within 3 feet or so to make it work on opening, and start it closing before I have even cleared the gates.

Also, If my neighbors are on their porch with their cordless-phone it won't work, and I have to remember my punch code. But, that is not a problem with the units that came with the gate.
