There are a bunch of different Cololights available, so Ill specify that I have the Cololight 7-pack Tabletop Kit, Plus. This includes 7 hexagon lights, one Controller Unit Plus, and a square base.I really enjoy changing the shape of my Cololight. The hexagons can be connected to each other in a variety of ways, and changing the shape is one of my favorite things to do when Im procrastinating. Its almost like playing with blocks, but cooler because they light up.I do have a minor quibble regarding the base. The power/controller unit fits through the center of the plastic base, but both are lightweight. If I make a design that is too unbalanced, the unit tips over. The USB cable connected to the controller unit is only 42 inches long, which might be too short for some setups. It barely reaches underneath my desk. No wall adapter is included.The Cololight CAN be used without the app. There are 3 light modes accessed via the power button: rainbow, sunrise, and mermaid. I dont really like fussing with an app, so most of the time I use the rainbow mode and thats good enough for me. I dont keep my phone on my houses wireless, so I have to switch to wifi to connect to the Cololight. The Cololight is not compatible with 5GHz WiFi.Connecting the Cololight to my wireless was a little janky, and the app could be better. The Android version requires an account to really dig into the tons of customization options available. The app is necessary to set a static color, or use the other preset modes. You can also make your own custom modes, including picking the configuration of the Cololight, to pick how the lighting flows up or down the shape.I honestly wasnt sure if I would use the Cololight very much, but I do turn it on almost every night while I work. It just looks cool! Even in the daytime, its bright enough to use in the sunlight.I just wish there were a few more built-in modes, or that the app was better. I dont like that the app requires an account on Android to try out all the customization options. Making my own presets required a lot of trial and error, because I didnt understand how to do things since the buttons werent all clearly labeled.
