These work pretty well. The coloring can vary a bit from order to order but overall works well enough. I believe some of these are just difficult to measure this way so not really their fault, but still usable. I very rarely need to pull out the pro kit.

Works great! Dip in water, add items for colors that dont match those in boxes. Turns jets on and wait 10-15 seconds to re-test. Colors for those items you added are now in the boxes! Easy peasy!

Easy to use and quick to read. These help me keep up with my pool levels without guessing.

Espectacular lo súper recomiendo a mi me ha funcionado hasta ahora y ya lo he utilizado en varias ocasiones yo le doy un 10/10

These work well and are really easy to use. Just dip and compare, and you get a quick idea of where your pool levels are at. The color chart is clear enough to read, and it makes regular testing feel pretty simple without overcomplicating things. I’ve been using them to stay on top of maintenance, and they’ve been helpful for that. Overall, a convenient option if you want something quick and straightforward.
