Review on 🎄 [2 Pack] BESTTEN Weatherproof Outdoor Plug-In Photocell Timer Switch with 2 Grounded Outlets, Light Sensor and Dusk to Dawn Countdown Timer, for Christmas Decorations, Green Color, ETL Listed by Sebastian Erik

Worked great. for the first three months. The photoreceptor suddenly stopped working. I installed it outside and hooked it up to a string of lights that lined the sidewalk to the driveway where we parked. The lens above the photoreceptor seemed really dirty, but after trying to clean it I realized the dirt was in there. The lens is just a disc of plastic stuck on with an adhesive that popped right out, and that's when I discovered that not only was the inside of the lens covered in dirt, but the photoreceptor itself was dirty and even had some sort of green mold growing on it . That. Washed with alcohol still does not work. I can turn it on manually and the mechanical timer function works fine, but nothing with photoreceptors works. So there's no auto-on in the dark and no auto-off at dawn. I think I'll try another brand.
