I just replaced the water filter and decided to check the water quality. I picked this brand because it seemed to have good quality. It's super easy to use; when I turn it on, the screen is green, and after the test, it turns red, displaying everything clearly. There's a water quality standard chart on the box, making it easy to compare. The value of 64 matches the bottled water output from the Haier filter, and 145 corresponds to the tap water data, which aligns accurately with the chart.

It feels a bit off. Pure water consistently shows as 0, and the same cup of tap water (well water) keeps fluctuating from 287 down to 79. I had a better experience with Xiaomi before.

This water testing pen is really accurate. It shows different readings for well water and filtered water, and even indicates the quality of water after using the filter for a while. Definitely worth getting!

A well-known brand you can trust, consistently accurate and stable readings after multiple tests.

This testing pen is super easy to use and shows results instantly when placed in water. The third picture shows the readings for unfiltered tap water, while the fourth picture shows the readings after filtration.

I checked the water quality, and the drinking machine downstairs showed a TDS of 14 after sitting for a day. When I measured the kitchen faucet water in a kettle, it read 209 when boiled, and a bowl of cold water was 131. It seems pretty accurate to me. The drinking machine’s TDS display has a small error of around 10, so measuring the water quality is sufficient. It's quite handy to use!

This water quality tester is definitely not worth the money; the readings are inaccurate, and it feels poorly made with lots of scratches, like a second-hand item. There's a big difference in values. It also can't be turned off manually. It came with two batteries stuck together without any protective measures, unlike other products that prevent battery drainage. Overall, the reviews seem overly positive, and this one was just a casual purchase.

The instructions are clear, it's easy to use, and the craftsmanship is impressive. I tested the water quality at home, and it provided detailed results.
