After 12 months of living on the broadwater, we were struggling with the mozzies and midgees and our little man is allergic so we were desperate to find something that works. We positioned this unit at the side of the house first which wasn't as effective, we then moved it to the water side. Seriously if you are on the fence, just try it. I have to say its changed our outdoor experience ten fold. We can be outside all hours of the day, after rain and never a mozzie or midgee bite. In addition to that, the midgees are no longer coming through the crimsafe mesh which has slighter larger holes than normal fly screen and we would have to shut the glass doors each day around 4pm which we no longer have to do so we get to enjoy the water breezes after nightfall. It's been worth every penny for us. We have quite a large block and the one unit does the whole thing. The refills have been easy to order also, so no complaints there. A1+
