Review on 📱 Wolo RC-100 Wireless Wizard: Ultimate Universal Remote Control System by David Caldwell

Works great. It's not exactly instantaneous as there is a relay inside. So if you press for a split second it will connect for about a full second but it's perfect for what I need. On a brand new car with a weak horn, I couldn't get to the factor horn or wiring without removing the bumper. Now I have two horns, one polite, one not so. :-) Button on the big side, about 2" in diameter, clamps on both power side wires would be nice
