I usually do my work at night and I am really satisfied with how these lights help create a very pleasant mood for my room. I love how well the lights sync to the app, and I find the "Tape" feature very cool as it syncs not just to the music playing in my room but also to my voice when I am talking. The lights are very easy to install, it literally took me less than 15 minutes. I love that the adhesive is very strong so I would not have to worry about the strips coming off the wall. The lights can be scheduled to turn off at a certain time and I find the feature very cool and helpful as I usually wake up late in the morning. The length of the strip is perfect. In fact, I only needed 3 spools for my entire room. The lights are also very responsive to the remote control. Overall, this is one of my best purchase so far and I highly recommend this product.
