The color quality and customizability on these lights are amazing. However, if you plan on doing any design that requires 90 degree turns then I suggest opting for leds without the epoxy coating on them. The coating makes it hard to do 90 degree turns. For example, I was working on a project in my room that had the leds go across the ceiling, and I had to 3d print special turn pieces since the leds did not want to work with the regular turns I had. If you are stringing these around a desk or the perimeter of a room they should work fine. With the latter, the corners wont be completely flush but will bend down to turn correctly.
