Excellent product, 100% recommended!!

Works great.

I tested tap water, bottled water and filtered fridge water...seems to be pretty accurate in the readings and easy to use.

Works like a charm!

I’ve owned dozens of PPM/EC pens, meters and testers over the decades and this is the meter recommend for PPM. It’s inexpensive and accurate enough for most homeowners or hobbyist. This has good clear readability and easy operation. Also just a coin cell battery so it’s light.PPM Meters all share one flaw — they are fragile and break easily! Expensive meters break just as quickly and easily as the inexpensive pens. They just aren’t buy it for life products.A budget meter will give up some accuracy compared to more expensive meters on the market but, the budget meter is still plenty accurate for a home owner/hobbyist. When it fails after a year or two, throw it out and buy a new one.My only complaint is that it doesn’t have a loop to attach a string to so I could hang it from a hook when not in use.

Works good.

I have an older water tester that gets different readings from 10-15 pts difference. This one is the newer one I have now which tests the water at a lower ppm rating.

This seems to be a very reasonably priced meter that works perfectly well for that price. We have a lot of TDS/EC meters around, some cheap some more expensive, and use them a lot, so we're pretty familiar with this tech. If you need measurements for your doctoral thesis, then you'll want something more accurate and you'll pay accordingly. But for most of the things most people want a TDS/EC reading for, this will work very well and there's no reason to pay more. I ordered two, and compared them with several other meters we have, some considerably more expensive, on several samples of water as well as against the NaCl calibration solutions we keep on hand. One was within 5%, the other about 7%, which is better than other similarly priced meters I've used, and for the ranges most people will see, no problem. The display is good. I didn't see any way to adjust the meter, so if it drifted over time, there's no way to correct it. But my experience is that unlike pH meters, that's rarely a problem with TDS/EC meters, so I consider that a minor complaint.
