I am going to replace 3 openers next month. I have eliminated Chamberlain because of the monthly fees. In shopping around, most sellers were recommending Chamberlain 's Group products. But they were unaware of the fee. As a result they are downgrading their recommending their products. Can't get an answer on 1 or 3 fees if I purchase 3 units from Chamberlain or sellers (ie Lowes, Home Depot, Overhead Door, various on line sellers).
