This is a tool I bought two years ago thinking it was too good to be true. I am a light hoarder and have the hardest time throwing out lights. I especially hate that all Christmas lights are LED and love the old fashioned incandescent lights that are no longer made.

This will repair most of your light strands that do not function. It will not fix all but for me it has fixed about 75% of them.

Again, thought it was too good to be true but every year is saves a few strands that would normally head for the landfill.
