Five stars. Very useful.
Measured the PH levels quite accurately. I have a digital PH reader as well and these strips gave me the absolute same results as the digital reader. Very inexpensive and quality made ph strips for sure. I'd recommend these to anybody that's in need of those. Can't go wrong. Better test your water before it's too late. You know what they say - better safe than sorry.<br /><br />I received this item at a discount/free in exchange for my honest and unbiased review. My opinions are my own and were not influenced by anyone or anything other than the quality of this product.
