Are Marantec garage opener and Viper garage opener the same?

Hi, yes Viper is private labeled Marantec. Here is the model conversion.

They are all 315 MHz. I would ask them if they have a circle of red dots display OR the small LCD screen first.

M4500e = Viper X50. Uses logic board 97798.

M4700e = Viper X70. Uses logic board 97798.

The was also one generation of Synergy motors (LCD screen) that was Viper X50 and Viper X70.

Use control box 116421 for logic board.
