 Virginia Tech was the first one to get one of our units, and they started to publish some of the research that they started to do three or four years ago now and showing how effective it is in crop types and things like palmer amaranth, which is a huge issue for them down there, and that was the main reason they purchased one of these. And they're showing results from 95% to 99% effective rate in the main weeds that they're running into out there.
