They are great easy to read results

I purchased this product and the AquaCheck brand test strips. I took water from 18 inches below the surface and used it to test this product, the AquaCheck strips, and then took it to my local spa store to have the water tested.This product is garbage for measuring alkalinity and hardness, they were hundreds of PPM off for hardness, and 100ppm off for alkalinity. The AquaCheck strips were much closer. Both were accurate within reason for pH and bromineGiven that this product is more expensive than the AquaCheck brand, I would expect greater precision. These are going in the trash, I will not purchase them again.

First time buying these test strips. They are not as easy to read as the other ones

I use these strips to check everything but alkalinity. Its just impossible to read alkalinity with these stips, I have other stips thatll say my alkalinity is right on and these ones won't even have it budge. The orange coloring for that part of the stip has very little color difference

These strips are so much better than the ones I have been using from my local swim store. They actually pick up bromine when it is 1ppm (I use the frog stick so I want to keep it a bit lower) I always had too much bromine with my other strips. I can actually read the ph and total alkalinity on these as well. It makes it so much easier to figure out if I need to address my pH or total alkalinity. I was guessing with my old strips and treated the wrong one half the time and spent days/weeks chasing the pH as a result. Definitely worth trying if you have trouble or are just not sure about the readings with your current testing strips.

I am very, very happy with these test strips. I have no problem maintaining my Saluspa hot tub. I trust every couple of days. My hot tub is used almost daily. When I use it every day, I test every day. My tub has remained crystal clear. I do shock it every 10 to 12 days. I adjust the PH and bromine levels, as the strips indicate. And my tub has been very easy to maintain, as a result. I am on my 2nd order of these test strips. There are less expensive test strips out there. But these have worked well for me and I won't change.

This was the first time trying these test strips and I found that they were easy to read using hues of various colors to indicate levels of pH, Alkalinity, Chlorine level, etc. The strips come in a sealed container and the color chart is on the side of the container. I liked these strips as they provided easy to follow instructions and an indicator of whether or not parameters are in range. So glad I tried this brand.

I like these. They tend to stick together, but all test strips do that. Color INTENSITY can be misleading - need to lay them on the chart to match actual colors, rather than the depth of color.
