  1. Uses 1 AAA battery

    Posted by Unemployed Rocket Scientist on 6th Feb 2015

    I bought this to replace the remote for my old (<1994) Sear 1/3 hp opener which uses a 9-dip-switch remote that I can not find locally or online. The shipping was timely and the packaging survived. It was as easy to program as advertised and as clearly explained in the documentation. I like the smaller size and the use of an AAA battery

  2. Trick to get it to work

    Posted by Unemployed Rocket Scientist on 6th Feb 2015

    I have an old (<1994) 1/3 hp Sears unit. I bought this to replace the Sears/Craftsman 9-dip-switch remotes which simply wore out and I could not find locally or online. Shipping was timely and the packing was protective enough. I had to use a tip I found online to get this remote to open and close my door: try each of the switch one positions if using your old remote's switch positions does not work. I'm pleased to have a small remote for my garage door.

  3. Good for the price

    I like the visor size remote, but needed on for walking the dog, this is much cheaper than Liftmaster's 890max and works good.
