I searched the internet this morning. Actually, I am looking for a mini-size / pocket size transmitter. It seems Liftmaster has something what I want (model 970CN), but I do not know where I can buy it.
I have check Sears, they have the "Clipper" but it is very large size. Regarding "Genie", I think they can operate its own brand or only one transmitter.
So, anybody knows where I can find the Liftmaster model 970CN?
