Rated 5 out of 5 by The tool repaired a bad section of my pre-lit tree! I found out about this tool by searching for "troubleshoot Christmas tree lights." I saw many hits about it and watched a couple YouTube videos (which I recommend to learn how to use it). I was amazed that it fixed a non-working section of my pre-lit tree on the first attempt! I had to go to three different stores to find one locally, and finally found them at Home Depot. December 8, 2014
Rated 5 out of 5 by Saving grace I never write reviews but this item warrants one! Been using it for years now. I've purchased them for friends and family, I've posted about it on Facebook. It has saved many prelit trees (mine as well as friends who have borrowed it), outdoor lights, prelit garlands, and numerous decorations. Totally worth it! If you follow the directions you can't go wrong. If your lights still don't work, then they just can't be fixed. This products will fix what can be fixed, but It can't fix something that is beyond repair. November 30, 2014
Rated 5 out of 5 by A Christmas Miracle What would have taken me hours in the past was cut to minutes with this tool. In the past it would be me and a volt meter going bulb by bulb trying to figure out why large sections of my pre lit tree would not it is done in just minutes....make sure after the lights come back on you replace any dead ones or you will have more go out November 28, 2014
Rated 5 out of 5 by This thing is amazing We bought this during the after Christmas sale 3 years ago. It took me 2 years to fully understand how this thing works but it definitely does work. If you have a string that is not working just pull a bulb out and plug the socket into the spot provided on the tester and pull trigger repeatedly until the lights come on. If the string of lights are divided into sections make sure you unplug one of the bulbs that is in the non working section. Make sure the string is plugged in while doing this. November 30, 2014
Rated 1 out of 5 by Hated it and threw it away! The best part of this product is that I purchased it online and picked it up at the store. It was great to just go to the service desk and not have to search for this item. The item itself was just awful and I literally threw it in the trash. It was useless. December 17, 2014
