Working way better than I expected.I use it to combine purified water and filtered spring water to get ppm from 130-150. This makes great espresso while reducing the solids being introduced into my ECM Casa V espresso machine. This practice makes my machine nearly never needing to be descaled with just enough solids to keep the purified water from leaching metal from the boiler.

Great product at a great price. Intuitive to use. Have to calibrate first. It comes with powder mix to make the 3 calibrations solutions but for under $10 I found it much easier to just buy the pre-made solutions also

5 stars well worth the extra money it works unlike the cheap 8 dollar one I picked up. This is easy to use, and I didn't need to calibrate it I had a test base of water, and it was spot-on.

I recently purchased the pH and TDS Meter for plant watering, and I’m extremely impressed with its performance! As a consumer, keeping track of pH and TDS levels is crucial, and this meter makes it so much easier.The setup was quick and straightforward, and the included calibration solutions ensured accurate readings right from the start. I really appreciate how simple it is to calibrate the device, which gives me confidence in the accuracy of the measurements.The pH readings are precise, and I can quickly adjust my fertilizer solution as needed. The TDS meter is also fantastic—it's fast and reliable, allowing me to monitor nutrient concentration with ease. Both meters are easy to read, and the display is clear and bright, even in low light.Another huge plus is the portability. It’s compact and lightweight, so I can easily carry it around my house without any hassle. The build quality feels sturdy, and the addition of water-tight seals makes the meter extra durable, even in humid conditions. I also love that it comes with a replaceable probe, which ensures longevity and long-term value.The meter uses 4 LR44 batteries, which are included, so I didn’t have to worry about getting the right batteries right away. The laminated, waterproof instructions are another thoughtful touch—they’re well-written, easy to follow, and perfect for long-term use in a home environment.Overall, I’m really happy with this pH and TDS meter. It’s an excellent value for anyone managing plants at home. Accurate, easy to use, reliable, and built to last—highly recommended for both beginners and experienced growers!

This little gadget is mostly fantastic—until it randomly decides to take a day off. When it works (which is most of the time), it’s like having a tiny, glowing oracle for my water. It tells me everything I need to know about what I’m drinking, except the meaning of life (though I wouldn’t be surprised if it tried).That said, there have been a couple of times it just refused to give a reading, leaving me staring at it like I’m negotiating with a diva. Is my water fine, or is this how supervillains are made? Who knows?Still, for the price, it’s a solid buy and does its job—most of the time. Four stars because even unreliable friends are still friends, right?
