Great product
Seems like a great product. It’s hard to double check but I did it twice and got similar results. I used it to brew several beers and it’s seemed to be spot on taste wise. It was very easy to use and better than a water report. It’s a great way to step up my game.
Nice kit. Easy to use

Be aware reagents have expirations dates
Be aware that you might get expired or close to expiring reagents in the kit. It seems they won't replace a item unless it's expired. This isn't a one time use kit. I purchased kit and received it a few days after black Friday. The Total Alkalinity Indicator expires 1/2019. First and last purchase with MoreBeer. Right on the Lamotte website it states that freshness of the reagents affect accuracy of tests. They list shelf life for each chemical on there website.

Not Worth The Money
Beware, aside from the initial purchase price, which is not cheep, you will need to continue to purchase chemicals that have a very short shelf life.
When I purchased my kit, it came with the total alkalinity agent already expired. I called More Beer and they were great! Apologized and immediately sent a new total alkalinity agent out to me free of charge.The new one came and it only has 2 months remaining before it expires and needs to be replaced. I checked on the LaMotte website and this chemical only has a 6 month shelf life.Many of the agents as they call them in this kit, have a shelf life of 12 months, so when you get them they will have to be replaced in less than 12 months. So again aside from the original purchase price, you will be paying $5 to $10 every few months to replace expired chemicals.I know many brewers don't want to use their local water test reports because there is such a large range/variance throughout the year. However, I found that I can call or email my local water provider, and they will give me the most recent test results for my water for free. Do yourself a favor and call your local water provider, ask for their quality control manager, and ask if they can give you the most recent results. I am sure they will be happy to provide them for you,and they will do this several times a year. I wish I had done this first, because I now have a kit, that will expire shortly, and I have no use for.

I got it to check my RO water.
My RO filter set up removed every thing from the ground water except the clorieen. but did reduce it by 2/3 of normal Now I know whats going on with my water. All grain brewing is all new to me and I now have the tool to do it right...

Works perfectly
I was able to gain insight into different water sources and adjust the water for the different styles of beer. The quantity of supplies allows for numerous tests vs just a few.

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.

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.
