I agree with that. It seems to work as advertised. When I calibrate my pH meter it seems correct and my plants will agree. However, the instructions say it should be used at a certain temperature. You may find this difficult to achieve. I had to buy a food thermometer to heat water to 78 degrees Fahrenheit. After that there were no problems. I'm glad I bought them and will buy them again.
