This is a terrible product that might work for a few milliseconds and then might not ever again. It is a shame, but it is not functional over any length of time. Ours lasted 1/2 tank of fuel, did great and then never worked again after emptying the dead skeeters out. Phone calls etc were just worse than useless. To Amazon's credit, I did get my money back. I would like to have something like this that did work.
