This might be the coolest light set I have ever had. I have the starter set and placed it on my mantle under greenery and it is spectacular. I downloaded the Twinkly app and now have so many options for color and effects. I also can create a design with the flexible tube and pair it with my own unique effect even having the option of creating my own effect using my finger as the paint. Twinkly flex tube is the perfect addition to spicing up my Christmas mantle.
