David U We have sold a few units. Right now have two in Jeff Foxworthy's new lake. I have to go back out b/c one is not working so hopefuly something simple. I also have to be honest other client in MS bought two and our water quality analysis showed not as good as we hoped. Bob Robinson with Kasco is working with me on trying to figure out why we are getting less than desirable results. I will keep you posted. I think Bob Lusk has seen some good results so maybe he will post them here if he has a few moments.
