Review on 🌊 Digital Water Tester for TDS and pH Measurement by Wendy Moore

Works great except I had no idea I would need to buy additional pH test bags if I want to use the pH meter after first use. The instructions clearly state that you should calibrate the meter if you use it frequently or if you don't use it for a long time. Um, that means all the time. I contacted the seller and he referred me to Amazon to purchase additional packs. I would like the item description to state that an additional purchase is required. Also, I tested the pH of several types of water and the pH meter showed very accurate results.
