Merlin C840, CM128 compatible remote control replacement transmitter, 433.92Mhz rolling code

they look great smaller than the original overpriced merlin remotes.had them set up and working in minutes so easy,with a greater range than the original. very pleased with the purchase.

I tried to set up today but it doesn't work at all. Definitely it can't replace the original Merlin one. It's a bad experience
