  1. Have not rec

    Works well with an average frequency strength.

  2. Works just fine - great value 

    Posted by RalphTheExpert on 15th May 2015

    Works with no problems on my old Sears Craftsman (Chamberlain)

    You will need a jeweler's screwdriver to open the case to remove the battery insulator.

    Opening the case was a 60-second pain. There is no engineered slot to stick a screwdriver or corner into.

  3. So happy!

    This replacement for my Sears Craftsman remote took less than 10 seconds to program and works great--at about half the price of the Craftsman replacement. One note: be sure to remove the little piece of paper from between the battery and battery terminal before trying to program it.

  4. way cheaper than liftmaster!

    I thought I was stuck with only the liftmaster clunky keychain remote that cost twice as much, thankfully I found this on their site. Much better!
