I bought one of the yellow pH meters when I first started growing basil hydroponically. It really confused me a couple of times, showing bad readings and making me change the pH in the wrong direction. If the yellow PH stick was a motorcycle, the new one is a sports car. She really does her job. It comes with a test kit and automatic calibration. It's just cool. dear company Liked the carrying case and plastic cheat card. Very very cool. Very pro. If you think this is a paid review, it's not. Check out some of the terrible reviews I've given other products. That's cool. I can even measure the pH of my tongue.
