I like the idea of those units but the price is more than I can afford. I need UCAs firts, and leaf springs next... lolI opted for a wireless remote unit to control my four lighting circuits. The unit is rated for 20 amps per circuit but I added a relay for each. My thinking is reducing the wireless to 1 amp or less should give my longer life. The unit has been 100%, only drawback is I do not have a indication when lights are on...unless it's dark out.
