Felt like false advertising as some tests consist of just looking at water and smelling it. I knew my water smelled. So I wanted to do a test to confirm it's sulfide. To put it simply: sniff the water and say the "test" test is ridiculous to them. My water has always had iron, but my water has never smelled before, now it does and I wanted to know why. Iron bacteria or hydrogen sulfide caused the smell. Who knows? You won't find anything with this test because you'll smell the water and learn that iron and hydrogen sulfide cause the odor. Well, I knew that before I bought this test. Super disappointed. They should say: test strips for 7 pollutants and advice on how to smell and visually inspect the water to see if there are other problems. This is very misleading
