after day 3 now neither work...not sure if it "operator error" but i have tried several variances of positioning in light and they just do not want to workOne set works great! The others did not but I am  waiting to see if it is because the box did not get enough light.  Other than that I am very happy with my purchase.  I will update to 4 stars once I know both sets work properly.



The lights are a lot longer than I thought so I was able to drape in the tree which looks great!   Received in 24 hours !!!
