Does the job

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?

Good product.

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.

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.

Not easy to read, not sure if product worked.
