A great aid to improve my beers
A very useful tool to detect changes and variations on the water profile, easy to use and accurate.
If you want to know the difference between a good beer and a outstanding beer!!!

Great Value, Excellent Kit!
Love this kit! I take regular samples of my brewing water to track changes over time. Much more convenient than shipping off samples to a lab. The kit has a very easy to follow guide for each water test. It’s very simple and well worth the money. I’ve gone through every test 7 times and I’ve used up probably 1/3 of the included solutions.

Easy to use, seems accurate
Instructions are well written and easy to follow. Test results were within range of reported values from water company and results have been consistent over multiple tests at various times of the year. Suggest using the higher volume marks (25 ml) on some tests to give higher test resolution. One note - the sulfate test readout can be a bit difficult to see in poor lighting.

Very Useful and Easy to Use
Admittedly $100 seems like a lot of money, but for the advanced brewer, I think this is a good deal. The quality of the kit is very high: the instructions are very easy to follow and not complicated. You also get a lot of reagent. That means that you'll be able to do a lot of tests. Doing tests repeatedly is a great thing, because water mineral content can change with weather conditions and changing water supplies.

The tests themselves (if you follow the simple instructions) are easy and yield unambiguous results, and the results I got matched quite closely to a report from Ward labs. You will not get the full range of tests or quite the level of precision that you will get from an analytical chemistry lab, but the precision is well within the bounds that a home brewer needs.

Finally, if you at all enjoy labwork, the tests are fun. All but the sulfate test use colored reagents and rely on titration. Doing the tests also helped me understand water chemistry a little better.

Excellent Purchase, Easy to Use, Useful
This water test kit covers the six major factors in brewing, including the pH factors (alkalinity, calcium and magnesium) and flavor factors (sulfate, chloride and sodium). Using your test results with one of the online water spreadsheets allows you to target your water to the beer you are brewing. The tests are accurate to 10ppm precision, unless you have very high concentrations, in which case you can either dilute with distilled water or perform the test at 25ppm precision. There are five actual tests, but other factors can be reliably calculated directly from those results.

Doing all five tests takes about twenty five minutes. Four tests involve dissolving a reagent in a graduated test tube (provided in the kit) which changes it to some bright color and then adding a different reagent, one drop at a time, and counting the drops to determine the ppm of the factor you're testing. Three of these tests are very easy to read; one (sodium) is pretty easy but not great. One test, sulfate, is different from the other tests in that you measure it by the opacity of the sample once the test reagent is added. I can't report on its ease of use because my local water has nearly zero ppm sulfate, which is totally clear. (I did try adding an unmeasured pinch of gypsum to that test and it went milky immediately, so it works, but I can't say how easy it is to read for practical purposes.) There is enough in the kit to perform at least 50 tests for each factor, so it should last me two to three years, and adds up to a $2 per batch cost.

This kit is great for me. My municipal water variably draws from no fewer than seven sources, including mineral heavy wells and soft reservoirs. It changes throughout the year, sometimes suddenly: since June, when I made my first batch until now (two month later), I have seen an increase in 40ppm alkalinity and 30ppm in total hardness. This a pretty major difference in minerals and it makes mail in tests basically worthless. I'm greatful to have a better analysis available to me.

Helpfull
Testing my brewing water is made easy with this.

Water is tough.
It is not easy trying to understand how water affects your beer. With this test i can adjust my water throughout the year depending on mineral content. Much easier than sending samples to a lab.

Helped me fix my beer!
I bought this system since the beer I was making (all-grain) at my new place wasn't up to my usual standards. After testing my water with this kit I determined it was pretty much impossible to make a decent all-grain beer with my municipal water. It saved me tons of headaches. I also sent a sample in to Ward Labs and I confirmed that this test kit was dead-on. Highly recommended.

I now test before each batch
I thought I had very good water, I live in Golden Colorado, and I have found out that my water chemistry changes by almost a factor of 2 with even minor rain storms.

The complete test takes about 10-15 minutes and then you can run the numbers in Palmer's spreadsheet and peg your water profile.
