I have chosen not to leave them up as I have existing hooks under my eaves. the lights are all facing down so I get the same effect. Just make sure you measure properly. I was short a few feet and unable to buy the extra strings due to low stock. However, I love the light effects and how you can choose your own colors and group colors and effects the way you want; all from the app. I especially appreciate the built in timers. No more programming a second timer, yea. These are fantastic and I will continue to add more as the years go by.
3m adhesive can be better, more clips to keep lights up, smaller string light extension under 16', some sort of splitter to run different section of lights,
Bought the outdoor permanent lights and love them. Not only are they bright but all my kids are excited about the colors change with each holiday. Another plus is they are hidden underneath the eaves of the house so i don't have to worry about hoa complaints
