Everything is great. Why they didn't see fit to include some sort of calibration formula to calibrate the pH meter is a real inconvenience. They don't tell you none of them are included, so you can order a few of them at once so you can start using the meter right away without having to wait days for the calibration powder to arrive. Shouldn't be too expensive. It would also be nice to have more detailed instructions for every 3 meters.
