Quality product
Does exactly as described, enabling me to chk when water filter isn't cleaning lime scale sufficiently, when it's passed lot of water and becomes saturated, saving having to change still working filter cartridge prematurely, saving money and the planet!

Bad water
If you have any issue with your water you need one of these to check to see if there is too many particles in your drinking water, i bet now you will be very surprised i was. We have gone from 300 particles down to 50 which is regarded as good drinking water. Well worth the money for a quick check, and really easy to use.

Fit for purpose.
Got this to test my RO water, works well tap water was 105 ppm waste from RO was 175 ppm RO water was 005 ppm. Okay it's probably not the most accurate piece of kit but gives me a good idea of my water quality.

No way to understand if water is good or poor.
I would have expected a guide to be with the instructions, like a range of good to poor.

Consistently reproducible results pre and post filtration
I used a Brita water filter for a while. I became concerned that the filters were not working. I switched to Culligan and using these, found the water quality was 102-120 pre-filter and 0-1 after filter. They reduce PFOS and PFOA which is more important to me than sediment. I'm a scientist and rely on instruments like this. It is very easy to use, is a great value to me. I find the results reproducible and believe the accuracy is good. I would buy again.

Necessary for those with zero water filters.
I use this with my zero water filter. I bought it to replace my old one that stopped working. This one operates the same and works perfectly.

Not the best for testing drinking water.
Accuracy is not the best +/- 50%

Water tester
This is a great little tool for testing your water. I use it to test my zero Culligan water filters when they start to taste unusual or off. It’s just nice to know that you can check your water. Easy to use my first one lasted about two years before I had to buy a new one very inexpensive.
