JNW Direct Hot Tub Test Strips - 100 Tests, pH 7.2-7.6, Chlorine, Bromine, Hardness & More - 6-1 Pack - JNW Direct

Good for daily use. Don’t buy more than one pot per year. They deteriorate

I ordered these test strips because of the great description they were given. Their performance doesn't even come close. I only use chlorine in my spa, yet I continue to get bromine readings on the test strip. They do not accurately reflect the chlorine level in the water nor do they accurately report the pH. Their app is also pathetic. These strips have caused me to have more problems with the spa water than I would have using another brand of test strips.

Great product, I order it often.

These will surely expire before I can use them up. I received these in Feb 2026. The expiration date is Jan 2027, and the manufacturing date is Jan 2025. I prefer buying a product that is closer to the manufacturing date than the expiration date. Even though the bottle was sealed, it indicates that these have been sitting on a shelf for a long time.

Great price for the amount you receive. These usually last me about 8 months
