I have used the Intermatic and the ACT/HomePro devices.
I now use (and prefer) the Vizia-RF line. The plug-in modules are smaller and the wall switches just seem to have a better look and feel. Some people do not like the way the Vizia-RF paddle switches work. You press the bottom and the switch goes to the opposite state of on or off. The dimming is done by a smaller two position switch at the side. Also, the switches remember their last dimmed state and return to that on the next on cycle. I kind of like that approach myself. My two cents.
