For those of you with Ecoxotic Stunner LEDs this is the dimmer for them. Its an in line addition that goes between the power supply and the LED strip. It has complete on/off capabilities as well as dimming. It is well constructed and it works without the shutter or jitter that many dimming switches have. It has positive clicks for full on or full off. It works as advertized. \n \nThere is one flaw that it very annoying though. The contacs are very loose and pull away from the power cord or fixture very easily. Nothing a little tape won't fix, but the connectors are simply not the same quality as the other Ecoxotic stuff I have. For I guess its pretty good. Just be aware that you mingt need to secure the connections.
