Hot Tub and Pool Test Strips - 6in1 Quick & Accurate Hot Tub, Spa, Pool Test Strips - 100 Water Test Strips, Water Test Kit with E-Book - Test Chlorine, Bromine, pH, Hardness, Alkalinity - JNW Direct

I found the colors are much easier to read on these straps. I was using aqua check but they were difficult to read bromine and ph reading was not right. These strips are cheaper and better product . I also used the keto strips and are great as well.

Muy bueno para medir la claridad y ph de tu jacuzzi.

First time spa owner! Just what we needed to keep healthy spa water!

Previous products from this company has been good; have not use this purchase as yet.

Un poco caro pero realiza su propósito gracias

I’m not sure how accurate they are but my pool watwe has stayed clean going off of what the strips tell me.

Product delivers accuracy. I was using accucheck and this product made me realize that accucheck was wrong. I knew something was wrong with my tubs systems and this confirmed it. My ozone generator was bad and so was my UV system. The accu check system said nothing was wrong

This seems to be accurate for testing my swimspa.

We were nee to owning a hot tub and had no idea how to balance it - these strips were so easy to use and very accurate. I recommend these!

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.
