I found this test accurate and easy to read, but the materials themselves are difficult to work with. There are so many bits and pieces to this test that you absolutely cannot lose. The dropper bottle was very loose, so even the lightest squeeze could mean a few drops would fall out too quickly to count. It was pretty bad because from the start you didn't feel like there was a lot of liquid in the bottle. I ran out of kit shortly after purchasing it and definitely got far less value from the kit than I did from API testing. If the set cost less I would buy it again but it's too much hassle and too little product for the money.
