2x LaMotte Insta-Test 4 Plus, Chlorine, Bromine, Alkalinity, pH, Total Hardness Testing

Recd the package today and tested spa water. Only had a few left that came with the spa. The free chlorine square fell off the paper strip. Tried a second one and same thing. Wow, these are garbage!

seemed to work but how accurate??

I have tried others, but the are a little over the top. This one is simple enough.

I love the product. Shipping was faster than estimated.

Test strips were as described. Came in good condition. Would buy again!

Favorite brand

Works good. Reading pH is better than others. Good for quick check, but we still use drops for better accuracy.
