Howdy! We have had a garage door opener from Liftmaster installed for over a year. Despite the low price, this device is quite good, and it was installed by a qualified specialist of the company for us. But just recently we had a problem with the fact that the device stopped responding to commands from the remote control, and therefore we had to call the liftmaster phone number and tell them about it. The next day they sent us a specialist who fixed it, and now the device works well.
