What a product. It is fantastic. It is the only Anti-Flea product that I have ever used that works 100% as described on the box. Do not wait if you got fleas, if you got animals you got fleas, you have to have at least one of these in the house. It really works. I assembled it and within 1/2hr I was seeing results. My only problem with it is the fact that the bulbs blow easily, however they are cheap enough to replace. The self assembly is easy enough, however be gentle eith the legs as they do not look too robust, check the other reviews for details. The one I have is working full time 24hrs a day, two dogs and two cats, and has made a huge differance in the house this year.
