These Famgee PH Test Strips are much quicker and easier than using the liquid tests, when testing my hydroponics set up.Because I've been using these types of strips for some time, I didn't need instructions. I also haven't found any difference in the results, whether I apply the liquid to the center versus dipping the ends of the paper into it.Because I'm not looking for a wide range of results, it is rather easy for me to see if I'm in the correct range or not. If you are looking for something more precise, a liquid test would be more accurate, and easy to read the results.You get a lot of testing strips, they are easy to use, and fairly easy to read the results. They work well for my needs, and I would recommend them!
