These lights are a masterpiece. I love the look and quality of them. They are so versatile and useful. The color choices are a dream as I can cycle through many rgb's. They can be very bright or even dim.
I like the 6ft legenth because I have a lot of lighting to work with. The only cons would be, using the 3m adhesive on the back. Simply it will not stick to anything. It's not good adhesive at all. I found myself attaching the led strip with clear tape. Also the lights can appear to be brighter from the side thats closer to the plug. Overall its a really good product and gives the wall fade a nice hue.
