Review on 🔒 Chamberlain Group CWA2000 Chamberlain Driveway Alert: Enhanced Security in Sleek Black Design by Jeff Bourke

Love it! I like the support of the manufacturers' products. refreshing. This product works exceptionally well. Period. Runs without hesitation. The device is battery operated, which means that it will continue to work in the event of a power outage. There is also a 120 volt alarm in the cab and a backup battery. We have a few of these and the dogs respond correctly to detecting alerts based on the number of horns they have. If the network fails, no problem. An important positive note in support of Chamberlain's product. The last device arrived without a spare parts package. The support agent "Sam" solved the problem immediately and without any cost or time on my part. Good news. Thanks Sam I will come back to find out more. Note: Use ENERGIZER AA ULTIMATE LITHIUM 20 YEAR BATTERY. Endure the winter cold. Replace every 12 months outdoors.
