In the beginning was very skeptical. However, because other options were eliminated, we tried this screw band. Pricewise not cheap, it was about two large flower pots (plastic, gray) stuck in the entrance area. Previously, we were able to search every day snails (slugs) from the flowers. After that there were only very occasionally snails in flowers. Works well for weeks. Have observed personally how hochkriechende screw on band "disgusted" turned away. Supposedly they get there electrical impulses that they do not like. I am really zufrieden.Meine wife thinks it can still quite good ,,,,. Well, matter of taste, but better than snails in flowers.
