My husband and I love these things! We now have 2, placed on either side of the house, such that they catch bugs from either direction before reaching us on the porch.  Although we can simply relocate them if needed, we still may purchase a few more - one to put back by the garage, and one by the back door.  I don't care for the octenol packs however, as I can smell them and they seem to choke me up a bit (they don't affect my husband).  However the light works so well, I'm not sure they are needed.
