on a good better best scale, Enerwave devices tend to be right on the edge between good and better, but are priced somewhat higher than most of the other “good” level switches, so as switches they tend not to be quite as popular. For example, you can get a linear/GoControl switch almost always about five dollars less then a similarly-engineered Enerwave.
Enerwave does make a number of devices which have features not available from other moderately priced brands, and those do tend to be quite popular in the community. For example, they have a good ceiling mount motion sensor. Also the Enerwave SC seven, which is a seven button wall-mounted device. They also have the only 20 amp zwave wall receptacle that I’m aware of.
But they’re just priced a little oddly. For wall switches, most sensors, and inwall receptacles they typically run about 15% higher than similar other brands like gocontrol or GE. So noticeably less than the high-end brands like Cooper, but they’re just kind of an afterthought in most of the device categories.
