We sell a steady number but more importantly we sell a regular amount of refills. I'll take that as a positive that it does work. The main thing we like about this system is it goes wherever your system does, as opposed to mist systems, which generally don't cover the front yard.
Plus the droplets are larger, meaning they aren't easily blown away by the breeze.
One thing to be aware of with anything trying to control mosquitoes: look at your neighbor.
If you are in a residential area and people keep their property in good shape then you should see good results.
If you back up on a marshland there is nothing to stop the mosquitoes from flying in for lunch.
