Bests & Worsts Reviews from Amazon

Wanted to check the status of my water filter and went ahead with this guy since there were so many rave reviews. But what I did not see was anyone posting reviews with actual tested data. This meter is a piece of junk and deserves ZERO stars! Purchased this meter and the calibration liquid that HM Digital CLAIMS to calibrate these with from the factory (SAME brand of meter AND calibration solution!). Well that has to be the biggest joke I have ever heard. Testing this meter out of the box gave a reading NOWHERE near the 342 ppm that it should have read in the test solution. So, I decided to calibrate it... well that was a bust too. Turned the screw all the way to the highest point it would turn, and this meter is still over 100 ppm off from where it should be. Literally a joke... Don't believe me? Check out the pics. Sending this stupid thing back today and finding one that actually works. You def get what you pay for... remember that!
