To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
Great price study does not leave any film or powdery residue or grit in products liquids as in of use in h20 or soaking verries etc get a longer hose thats not to say the hose had any problems to short for my applications 😊
I have not used the replacements yet, I have to say that the machine itself is outstanding. I Purchased this at the recommendation of my holistic doctor. Being I couldn’t get to his office he recommended purchasing this machine for the ozone treatments. I use it on both of my dogs who are ill as well as oxygenating my own food. It’s been a couple of weeks and there’s been a dramatic difference.
