Review Updated: Received a replacement meter from the company and it is now working great. Thanks very much! I was having issues with plant nutrients so I ordered this meter to see how strong my mixes are. Right out of the box the meter didn't read when I put it in tap water. I turn it off and on again and then it started reading, so I made my own adjustments and felt very good with the readings I got. I then turned it on for a second use and it stopped showing, just 0.00. I replaced the factory battery with a new one and received the same one without reading anything at all. I left the meter overnight and came back the next day and when I tried this time it worked! So it gives me consistent readings which I believe to be correct when it works. So if this meter didn't turn on and work it would definitely get 5 stars because I was able to diagnose and fix my plants water and nutrient issues very quickly.
