Review on Koopower Outdoor Operated Waterproof Decoration by Jennifer Groom

These lights worked great during the outdoor holidays. I have put them on wreaths outside on the windows of my house and the timer function worked on all of them every night (I bought 2 packs, used 4 garlands daily in timer mode). The batteries lasted until Christmas and a few days after New Years. I wrapped each battery box in several layers of plastic wrap to really weatherproof the battery boxes in the Northeast winter. I don't think I'll need it because the battery compartments have a silicone seal inside, but I'll be doing the same thing next holiday season as the extra protection doesn't hurt and it's so easy. I recommend to anyone who needs outdoor garlands with timer function and multiple lighting modes to choose from.
