I was wondering if anyone has any thought or input on this product from Missouri Wind and Solar http://mwands.com/store/pond-aeration-kits
and here is a short youtube video showing it work https://www.youtube.com/watch?v=7xtxo7aJmnA

It is a fraction of the cost of other solar units (about 800-900 dollars after addition of solar panels) I cannot find any reviews of anyone who has used it. I am trying to find an aeration option for a northern pond where electricity is not an option.
