This is well worth your money. We did have a problem that it didn't work because of the fan, we found out, but we shipped the head to Mosquito Magnet and they returned it fixed in a week. Two days after we set it up we hardly had any mosquitos in our yard even in the front of the house. It's been running for a little over a week, and I can be outside without having to swat away any mosquitos even at dusk. And before we set it up, there were tons of mosquitos. We couldn't swim in our pool at night unless we sprayed Yard Guard because the mosquitos would be swarming around our heads. Now we don't have to worry about getting any diseases. The only thing you need to do is figure out your wind direction and where to set it up so that it works properly, but their internet site will help you with that.
