    The strips work so if you are not getting a good read then it IS THE WATER!!

    Funny thing was for a month I was not getting a read on the Bromine at all, like nothing. I was unsure what to do so since there were only 10 that came in the Spa Choice Kit I ordered more and tried again still no luck. Literally everything else was perfect but no bromine. The after a shock test from theomine kit and added two ore tablets I got a perfect reading. Yahoo!

    Color development seems to be better for pH and alkalinity than some other test strips ...

    Color development seems to be better for pH and alkalinity than some other test strips I've used. Free Cl is also relatively easy to read. Mainly, though, I find the reagent chips do not bleed, which helps reading clarity a lot. So, as one of the less expensive test kits, I think this one is a bargain.

    LaMotte is better than choices from big box

    accurate. however, I like Lamottes with more features, items to check. hard to find.

    Best pool test strips!

    I could not find these strips last year and ordered others that were more expensive. The more expensive ones did not work. I found these again this year and purchased them. They are the best for testing your pool water. They are very responsive and easy to read.

    This is a must have for hot tub owners. Same product as at the local pool shop. Very accurate as compared to water testing at pool shop. pH a little difficult to read due to how close the colors are. Recommended.

    Good price for daily limited info test strips

    I use a chemical test kit weekly but like these for a quick check daily at reasonable cost. I also alternately use the other more detailed LaMotte strips that give more information but cost a little more. They save the cost of replacing test kit reagents as frequently and always give reliable readings close to the reagent test kit readings. Judging colors for accurate information is reasonable considering the substance being tested and the limited concerns for accuracy varience.

    We have tried a few others but this came out on top

    I use these for my plug N Play hottub. They are what the store we got the hot tub from recommended. We have tried a few others but this particular one is very user friendly in comparison. Perfect for those who are new to the testing of water and balancing chemicals.
