I think this is a great product. It comes pre-calibrated and I haven't had to calibrate it since I bought my first unit about 3 months ago. I bought 2 more and use 1 for each of my nutrient stores. I've found that being able to see the PH reading without having to disassemble the PH meter saves me a lot of time. The meter comes with a temperature sensor so it provides a temperature corrected PH reading. Overall I think it's great value for the amount of time it saves me.
