Merry Christmas to us, our presents to each other this year. Lack of remotes prompted us to finally upgrade our old door openers. We had never installed door openers before but decided on a weekend after receiving them to try and save ourselves at least $200 by doing it ourselves. The first one took forever, but the second was "relatively" quick. Be sure to look closely at the illustrations if you've never installed one before. We were replacing (two) an old--very old but well built--overhead door model and a genie model. Neither had remotes. The genie needed a new board if we were to have a remote. It seemed a better idea to replace it, after 15+ years. Very happy with these openers, very quiet. Heavy duty model has a better warranty as well.
