I first wrote a review saying I was disappointed with the product. After further consideration, I've decided to repost the review and hopefully encourage the manufacturer to include more detailed instructions with the product. I learned from another test strip company that provided instructions that there were temporary differences in results when the water was deionized or ionized. While I cannot fully endorse this product, I would like to acknowledge that there are other factors to consider when it comes to water testing and accuracy.
