The idea is great, the function also. In my 150er galvanized iron gutter unfortunately fit difficult over the bead. As mentioned in the other reviews they break also like by and are then useless. I needed 25 (distance 25 cm), and who are 5 pieces broken because I ordered 2 packs because of the Notes was not a problem. Have here a freezing rain fairy lights hung and am extremely happy with the result.
