The color change is nice and clear, and it's very simple to use. Liked about it Easy to tell when the color changes *Inexpensive *Great for getting a quick reading Didn't like Only reads in increments of 1 dKh, so it only gets you a ballpark estimate of your alkalinity Overall rating:   4.5 Overall satisfaction:   4.0 Would consider buying it again:   5.0 By schneijt Oct 01, 2009   Ask schneijt a question about this item.

This is one parameter that I like to have more than one test kit for. I typically have a higher end kit and this kit. I feel that this kit will get you in the ball park, and is usually reliable. But for the price of these its worth the piece of mind to have a second opinion, especially if you get a odd reading on the first test. Liked about it I like that they are inexpensive, and you get a good number of tests out of one kit. Also the color change is obvious and clear. Didn't like The only thing about these kits is that they only read in 1dKh increments. But for the price its still a great kit.

Liked about it cheap easy to use clear consice instructions. Didn't like they may not be as accurate as some of the higher end tests.
