UPDATE 2: about 2 1/2 years in use. I never had to change batteries and used the light control several times a day. However, recently one of my light controls went off after touching the screen with my fingers after applying skin lotion to my hands. Somehow the skin lotion destroyed the touchpad. This was not to be expected. Tried changing the battery, no success. It's toast now. I'll buy another one and try not to touch it unless my hands are completely dry. Please note that I have been using many of their bulbs for over 3 years without ever changing a single bulb. All of their lights work great. They make great lights. UPDATE 1: I have 2 of these now, they work perfectly 100% of the time. The first one has been running for over 16 months and still works great and I have never changed the battery in that time. Phenomenal battery life. First of all, the Mi.Light B4 wireless wall light control panel looks very nice. The photo of the product is not true. The glass touch interface is beautiful. For some reason the photo of the product makes it cheap. It doesn't look cheap at all. Management works great. Light control setup takes only 3 seconds. This gives you 4 lighting zones for independent control. Each zone can control an unlimited number of lights. We're literally talking about hundreds. If you have multiple lights that need to be controlled in sync, Mi.Light is one of the best wireless light control systems available for the price. You can also use any number of controllers paired with the same light or sets of lights. For example I can connect this control to a set of lights on channel 1. And then connect another controller to lights on the same or different channel and control that group of lights independently from the two controllers. This allows you to have wireless lighting control at two ends of a long corridor, both controlling the same set of lights. Very cool. I chose the battery-powered version. The controller lights up and makes noises when used, which drains the batteries. I don't know how long the batteries will last. Just take a look.
