First off, this Mi.Light B4 Wireless Wall-Mounted light control panel looks really nice. The product photo does not do it justice. The control's glass touch surface is beautiful. Somehow the product photo makes it look cheap. It does not look cheap at all. The control works great. Setup to control lights takes only 3 seconds. It gives you 4 zones of lights to control independently. Each zone can control an unlimited number of lights. We're talking hundreds, literally. If you have a ton of lights you need to control in sync, Mi.Light is one of the best wireless light control systems available for the price. You can also use any number of controls paired with the same light or sets of lights. For example, I can pair this control with a set of lights on channel 1. And then pair another control with the lights on the same or different channel and control that set of lights from the 2 controls independently of each other. This makes it possible to have a wireless light control at 2 ends of a long hallway both controlling the same set of lights. Very cool. I opted for the battery-powered version of the control. The control lights up and makes sounds when used, which will drain the batteries. I don't know how long the batteries last. We'll see.
When the lights are off at night you cannot see the switch to turn them on.
