Not very precise and kind of hard to read
I appreciate what this kit measures, but the precision is lacking. It's generally in 10ppm increments, which is good enough to get by, but not good enough to improve on the annual report from my local water district. So it wasn't worth the money and I decided to return it after one use.

The regent colors are also pretty dull in some cases and hard to tell when color has actually fully changed.

If you can't get a district water report, this would probably work for you. If you can, there's no reason to get it.

Good Kit
Easy to use and gets you results in 20 min first time. You can make it faster once you get comfortable with all the process.

Overall - I like this kit. I don't have a lot of experience with other water testing kits, but it seems to work well and is pretty easy to use.

The only thing I would change would be to include a color target. Many of the tests have you add 5/6 drops of a certain substance to the water under test, which will change the color to, say, purple. Then you are supposed add any number of drops required to change the color to say, blue. The hard part is that my perception of blue may be different than yours. Having a color target of the expected blue would be helpful to say that the water under test has reached the correct color. Now count the number of drops and that is your ppm concentration of the say chloride. Additionally, my sulfate test was almost indistinguishable from the 0-25ppm test, meaning it is anywhere in between. This makes it kind of difficult when trying to figure your sulfate / chloride ratio.

A good investment
Quite good. Easy to follow, but lacks a little on the accuracy. I would recommend this to any home brewer.

Excellent water test kit that allows you to understand your water chemistry and deal with it on brew day. So very easy to use with the included instructions and is a lot cheaper than having your water tested by a professional, who is going to use a similar technique. If you understand the importance of your water on your beer and you understand how to treat your water then you need to have this kit.

I really liked the Brewlab. There was a very small learning curve, but the testing is very easy after the first or second time.
