Query: Great if you can get one that works

I ordered the sending and recieving units together as a package about 2 months ago. When it arrived it sent up a bit of smoke and stopped working about 30 minutes after we installed it. Chamberlain was very friendly and sent a replacement which took about 2 or 3 weeks to arrive. This time the microphone in the sending unit didn't work! I sent it back and about 3 weeks later they sent me just the sending unit! Finally they sent a package with both the sending AND recieving units. One of the recieving units was dead! Fortunately, I at least have one sending and one recieving unit which are working. Costumer service is friendly and they try to solve problems, but it seems that there is absolutly no quality control with their product. So now, I really don't trust their product. When it works it is great....but I wouldn't recommend it.
