I had to bump heads with my wife to get one of these biosonixes. Had to defy her "authority" and get one against her will.
I been using it since Feb. I haven't been impressed. I even called the folks for extra tips. Any time I was doing exceptional on the water, teams that did not have one always had more. And of course my wife likes to rub my nose in it.
I have tried to keep an open mind. But.....I have to give this product a big Thumbs down.
Lots of folks have been beating me on the water without a biosonix. Perhaps I just am not using it right, and to be fair, I am not the almighty KVD.
