Review on 📈 HM Digital TDS 3 Handheld Carrying - Enhance Water Quality Monitoring on-the-Go by Ryan Olsen

I just received my new TDS-3 and tried it for the first time with HM-342 calibrant and got a 320 displayed. But a few minutes later I tried the solution again but it showed 440 then a few minutes later 510 and kept reading 510 so I waited another 30 minutes later now it's 477. Same discrepancy with my faucet water. First it was 188 and a few days later it was 147. The same cup and tap water in the kitchen sink. But not with my distilled water. It consistently reads my distilled water at level 2 every time, whether I do it now or 10 minutes later. I have 2 different brands of distilled water: Walmart distilled water reads consistently at 0 each time; and my distilled water, which I make myself on my distillery, reads every 2 inches constantly. I spoke to the manufacturer and they said the photo on the description page is real and original but the product they ship is NOT. I sent them photos of the meter this seller sent me and the manufacturer said it was fake. The manufacturer said if it's genuine 1) it will read "HM" when you turn it on and then show 000 a second after that. 2) It also has 5 bumps on the edges on the left and 5 opposite bumps on the edges on the right (you can see them if you look at it from the front). the back. This product sold and delivered here has NONE of the 3 characteristics listed above and is in fact a counterfeit. I returned it.
