We have a cherry tree that attracts pretty much anything with wings and while we don’t mind sharing some, the birds tend to be a bit greedy. We’ve used pie tins and other reflective devices in the past but they end up too large and get stuck in the leaves rendering them useless. This kit did solve most of that problem by having various shapes, sizes and angles of light reflective-ness. The tape is a nice touch and I do appreciate the diamond shaped pieces coming separate so you can customize the length of each piece in the event where you have some shorter areas between branches.Overall very satisfied with the quality of the reflective surface and confident the birds will choose another tree to feast in.
