Product review (5 stars): VERY VERY VERY VERY WHITE laundry using this device!!!
It took only 10 minutes to install the device. I immediately ran a small load of white laundry in cold water using 1/4 capful of detergent (I just wasn't ready to cut the cord on detergent just yet). I have a front-load high-efficiency washer and it starts its cycle by filling in short spurts. Each time the water started moving, the pureWash window lit up blue and I could watch the water go by infused with loads of oxygen bubbles. At completion of the wash, the laundry and drum smelled surprisingly clean. I moved the laundry along to the dryer and started the dry cycle. Upon completion, there were two things that were VERY apparent. First, the whites were big time WHITE!!!! Secondly, the laundry smelled very fresh. I have to admit I do not agree with Consumer Reports on their evaluation of this device. Their claim is it only cleans marginally better than regular water. I say that's a big bull-oney sandwich as my whites are VERY WHITE using this device....and without using bleach!

I suggest buying from  OzoLaundrySolutions  for best pricing and fast shipping.

One week later:

I've laundered a whole bunch of items which include both colors and whites. First off, as I stated above, my whites are WHITE!!!  Now that I've laundered some colored items, I say they are much more brilliant than before. That's not to mean they are faded, it means the colors are vibrant! I have some very colorful tropical shirts and they are turning out bright!! I also laundered my bedding, which includes foam-top mattress cover and pillow covers, sheets and pillow cases. They came out of the laundry smelling clean. Not a clean as in a "scented clean", but as in a "no odor whatsoever clean" which I like. I'll make it a point to provide an update in about a month.
