"I got an invitation to review this switch. It would be rude not to accept. I used it to replace a dimmer switch that no longer dimmed. This one has been in use for 2 weeks and does just what I expect it to. It turns the 6 x 50 watt halogen spots on and off and makes them go dim or bright as I turn the knob. Is it reliable? Ask me again in 2 or 3 years time, but so far so good."
"What can I say? It switches light on, dims it and switches light off. Well made with no rough edges, nice feel to rotary control - positive rotary action with slight friction so is easy to control dimming. Good value."
