I researched garage door openers for a few weeks before deciding to purchase a Chamberlain. The Genie that was being replaced lasted 15 years, so I was initially tempted to stay with that brand. I wanted to avoid a chain driven model due to the noise that is generated. The Chamberlain was on sale at an incredible price so I opted for it. Installation was easy up to a certain point. I assembled and installed about 85% of the components. I eventually had to pay a handyman for 30 minutes of work to finish the job. The unit came with 2 remotes as well as an outdoor panel. I highly recommend purchasing a garage door opener with the outdoor panel. It is nice to have the keyless option after hiking and running. The whisper drive is pretty much as advertised. It does not reverberate nearly as much as the original chain driven model. All in all, I am extremely pleased with the unit, the ease of operation, and the price i paid.
