Two years and we still love it! All the lights work. The remote that handles all the color changing and speed of blinking is great and can be placed away from the tree so presents don’t get in the way. Every day we choose a different color or setting for the lights. Every year around 12/17 we start leaving it on 24hrs. 
We haven’t had an issue yet and if I ever need to replace it, I know where I’m shopping for one.
