Works very well and easy to read.
I got this as the copper strips that came with my copper ionizer weren't easy to read, like the color scales didn't match the results. These strips are very easy to read and work well.

One note for hot tub users - unclear directions
I'm generally happy with the product, but I wanted to point out one thing that was unclear about the instructions.The directions say to dip the strip for 15 seconds in 75 degree water. The first time I used the product, I thought that meant I needed to draw out a sample and wait until it cooled to 75 degrees. After further research, I learned that the dip time varies by water temperature, and the manufacturer provides a table of instructions that specify the dip time by temperature. For hot tub water (95-105 degrees usually) the dip time is just 10 seconds.
