It's great unless it's defective

The unit is large and clumsy. I initially installed it and it didn't work. I checked and rechecked my wiring. The unit wasn't generating a 12v switched signal and the door chimes didn't work. I woke the next day to a dead battery. I decided to run a 12v switched feed from my ignition bypassing the unit. The next day I had another dead battery. The unit was causing a relay to fail and drawing 1.7 amps all the time.

After returning the unit for a replacement I finally got everything working properly but my 3 year old battery wouldn't hold a charge after 2 complete drains. I then had to buy a new battery.

I've had it for about a month now with no issues. The bottom line is if you get a functioning unit you're good to go. The new one works perfectly as it should. If you get a bad one just a remove it and be patient. Trying to work around a faulty unit just isn't going to work out.
