Took a few minutes to learn how to use it but after that super easy.

I’m very happy with my purchase of the Taylor K1005 9-Way Test Kit. The price was reasonable, the shipping was impressively fast, and everything arrived in perfect condition. I also appreciate being able to support a small business instead of a big-box store. Highly recommend!

If one wants to have perfectly balanced water then more accurate & reliable water chemistry testing is needed, and this kit fills that need perfectly. Therefore I consider this to be a “must have” item for all Hot Tub/Swim Spa home owners.
