Bests & Worsts Reviews from Amazon

I purchased two and thought to only open one to see how it performed prior to opening the other. It was easy to put together oh, easy to turn on, easy to place on the patio table. Even after checking to see that does start button had been engaged and hearing that it was working, the mosquitoes continued to swarm our patio area. Mind you we are sitting three feet from this thing and the mosquitoes we're not bothered at all. It has a 15-foot radius according to packaging and advertising yet within 3 feet the mosquitoes are having a field day. Needless to say the extra one is being returned.
