EEtsy"We had a group of young foxes visiting our garden every night and damaging the plants, and nothing seemed to keep them out. I attached a few along the fence, and they worked brilliantly! The foxes stopped coming! Easy to install, great design and well crafted, and genuinely effective — highly recommend."
