First of all, the lock is very solid. Second, the installation instructions were easy to follow, the online video even easier. Third, every part was included in the kit, the template worked perfectly, the included 1-inch hole saw cut the hole in the metal door track in all of about 10 seconds, so to those suggesting it wasn't adequate to do the job, ignore them. Wiring was easy. Installation of the sensor and power unit as well. My garage door opener does have a battery backup system, so I used the included cable to connect the locking sensor to the backup battery -- again, easy to do. Following the instructions for activating its initial run is important. I cycled the lock through several cycles, worked perfectly. I had a question for tech support, sent an email, had a response within an hour or so. Nothing to complain about when your questions are answered quickly and accurately. All in all, I'm very pleased with the added security this lock provides. I'd recommend it highly.
Works as it was designed. Extra security needed for our garage door. Perfect! Easy installation.
The lock mechanism itself has a self-evident operation and mechanical override. And for self-installers, the kit includes the bit needed to install the lock on the door track. The technical support for this system was fantastic!!
