I have installed the M2000 , the pixel and smartrise V2 . And I do agree with a few of you , stay away from the C4 hydro or traction from smartrise ( disaster ) . We ended up using pixel for years on hydro and its user friendly , but until we start using a new controller this year Alpha Control , my boss ordered it and of course I complained , but after installing a few of them I love it , the product is fantastic and the tech support is top notch. The bluetooth software upload is a game changer ! .
