We found that its Posi-lock anti-theft protection gives 100% assurance that only you can operate the opening and closing of this door and prevents forced entry. Once the door is safely locked, it remains locked. Unmatched and trusted security+ 2.0 code encryption prevents any type of hacking. And last but not least, dual-function wall control gives access to control the opener lights and even permits you to lock and unlock the garage door from inside the garage.

The most annoying part of lifting garage doors is their creaking noise. But we love B503 myq smart garage door opener Chamberlain for its ultra-quiet and smooth performance because of its belt drive type. It is so inaudible that while experiencing it, we experienced that we have experienced absolutely no sound while this opener is running.

Another thing is the protection system of safety sensors with quick-snap brackets. We saw that this garage opener exhibits an invisible light beam across the door that breaks down mechanically with any kind of interruption. Accidently, if any person or any object comes in contact while closing the door, its sensing technology will automatically reverse the door.

6. Smart Control

Chamberlain MyQ garage door opener B503C can be controlled via remote, MyQ, and Homelink. Its three-button garage remote can be operated easily with a long-life lithium battery and visor clip included in it. This super range Chamberlain remote reaches 1500 ft, which we found is very convenient for swift in and out of the garage.

Apart from its remote access, you can also add MyQ smartphone control with MyQ smart garage hub. When we tried our smartphone to open and close our garage door, it was a smooth operation. We can also reschedule our garage doors closing, and lights turn on/off in our garage with our smartphone.
