DMight Pool Test Strips, 6-in-1 Water Quality Test Strips, Spa Test Strips for Hot Tubs - Total Chlorine, Free Chlorine/Bromine, pH, Total Alkalinity, Cyanuric Acid, Total Hardness.

Have used many many test strips over the last 30+ years and these are simply not good. I can’t recall strips that bleed as much as these. When trying to get a reading and compare it to both the test from my pool store & my own drop test kit I found the colors on the strip aren’t in the ranges in the gradient values. The comparison colors for the gradient values on the box and bottle don’t really match each other so how can you get an accurate reading?

You’re not supposed to touch the pads when using these strips, but the pads go from one end to another with no where to hold the strip.

Readings are not accurate. Several turn colors that don't exist in the chart. I know this from comparison tests with a known strip that I have used for years but can no longer get.

Does the job

Not easy to read, not sure if product worked.

Good product.
