So far so good. I was looking for a connection box that would allow me to install an outdoor lighting under my Pergola. It has been installed for several weeks now where the boxes are exposed to rain, and NO problems so far - thus the reason for the water resistance score - time will tell. I highly recommend the "Brightech Ambience Pro - Waterproof LED Outdoor String Lights - Hanging, Dimmable 2W Vintage Edison Bulbs". If you are interested in a project like this one, the picture shows my pergola with light, junction boxes, and a porous cover. Two junction boxes identified with arrows.
