Product review (5 stars): This product works like I hoped it would!
I recommend researching your existing washing machine more thoroughly than I did. Because my top loader was old, and did not say HE on it; I figured that it was not a high efficiency washer. When I hooked this model up, the bubbles were very mild and I could not smell any ozone. I later found out that I did in fact have a HE washer. So I gave it to a friend for Christmas who had a regular washer. It worked perfectly! I later ordered the proper HE model and love it;  I will review that separately. He has a slew of "healthy alternative" products and had never heard of anything like this, although he had been off main stream detergent for years (unlike me); he is very happy and thanks me regularly for it.

Cleans clothes very well, gives 2nd rinse more cleaning ability (as ozone is used an additional time), removes all odors and performs the same way my detergent did. Still need some stain remover from time to time, or some really good natural soap for soiled loads.

Company is very responsive, I was able to get on the phone with an engineer to ask questions before I bought it. Contacting tech support later was just as easy.

It is easy to install, I did wind up getting metal fasteners instead of the plastic ones they include; but this thing is not very heavy and doesn't really need anything more than plastic fasteners.

I really like to see products like this, keep em coming!
