These are the best lights I have ever used.  They come in long strips, very well made and you can cut to the length you need.  The app that you use to control them is very intuitive and easy to use.  The array of light colours are limitless and fun for any mood.  The Alexa is also an added bonus although we haven't hooked that part up yet.  The adhesive tape is very strong and stuck immediately.  These are worth every penny!!!!!
