Review on Industrial Grade Outdoor Extension Cord Splitter for Multiple Devices and Outlets by Mario Beckwith

I have used it for outdoor Christmas lights in the cold and rain with no problem. I didn't even bother to waterproof the connection and it still worked with no issues. Works as expected. As this was used in my stone bed I buried them and will just leave them as is until I need them for the next Christmas holidays. Seems solid enough to stay out all the time.
