Review on ACTIVE Insulated Water Bottle Stainless Kitchen & Dining by Ben Chase

I've used it during the day and at the end of the day, although I have to test it. I have a reverse osmosis system at home that makes the water acidic. My test strips show a 5 for reverse osmosis filtered water and about a 7 for unfiltered water. I've used this product on both filtered and unfiltered water and it hasn't worked. Very disappointed. I have tested several times and the results have not changed. However, I have to say that this is not a total loss. I ended up with a very expensive steel cylinder. I do not recommend this product.
