Excellent product for measuring chlorine in water. This digital reading eliminates all guesswork and requires no sunlight to accurately match colors for reading. However, it uses up sachets of additives needed to measure chlorine in water, so I recommend buying enough sachets for the test. Another recommendation is to do this test about once a month and use other quick test strips.
