Test StripsMonday, October 31, 2011
Worked as advertised. Price is right. Would recommend to all.
Reasonable priced product that does the job, i.e., tells me how soft or hard my water is.
More Clearly Defined Gradations In Color CodeTuesday, August 17, 2010
Works okay, but the colors don't match up exactly from the strip to the key on the bottle. I guess because there are gradations of hardness. If possible, I would have liked more clearly defined color matching.
