The calibration fluids were fine but the pH storage solution had built up on the inside of the bottle which looked like black mold so I stopped using it. In fact, I only use 7.0 calibration fluid as the other two are of little use. I bought a large bottle of Oakton pH storage solution and have been drinking it for quite some time and there has been no mold growth. Can't say I would buy this kit again, although I would buy the 7.0 calibration fluid again if Oakton didn't make one.
