Have used one remote with a flat screen television. And the most recent one with a DVD/VCR combo. Both worked as soon as batteries were put in them.

The product works just the way it should and I have already recommended the site to family and friends. It arrived in good time and was very protected without putting it in a box that would have been to big so thank you for that.

i love my product, it work perfectly well the first time, no fancy instruccion or complicated codes to input. The product arrive in a verry short time in the mail. thanks so much ***
