Review: Looks cool and works great. - UPDATE 2: used for about 2 1/2 years now. I have never needed to replace the batteries, and used the light controls every day multiple times. However, recently, one of my light controls went dead immediately after touching the screen with my fingers right after applying skin lotion to my hands. Somehow the skin lotion killed the touch panel. This was not expected. I tried replacing the batteries, and not such luck. That one is toast now. I will buy another one and make sure not to touch it unless my hands are completely dry. Note that I have been using many of their light bulbs without any problem for more than 3 years now without ever replacing any of the lights. Their lights all works perfectly. They make great lights. UPDATE 1: I have 2 of these now. They work perfectly 100% of the time. The first one has been working for over 16 months now, and still works great and I have never changed the battery in that time. The battery life is phenomenal. 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 to 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 lasts. We'll see.
Review: Perfect control - Works great. Colored lighting is very rich, but can be controlled as desired. Most Happy with quality and price.
