G Baker: Go this tester since I converted my pool to a saltwater system. This tester was easy to use right out of the box with no calibration needed and was self explanatory. Display is large to read that was backlight to know what function you are on. Scrolling through the various test was a breeze.

SF Gator Mom: We recently had our pool redone and have to keep the water balanced for our warranty. So instead of going to the pool store every two days I can now go every five days using this. We didn’t need to calibrate it. It was already done and the easiest way to check it is just use fresh vinegar. It’s actually easier to use than you would think because they make it look complicated. I would definitely recommend this for your pool

KC: I recently purchased a Water Distiller and I wanted to make sure that it really was working. After doing some research I ended up purchasing this TDS Meter because it got so many great reviews and it was a really good price. I'm not trying to use Meter for any crazy science experiments I just want to make sure the PPM of my distilled water is low so that I can use it in my Espresso Machine and my Ice Machine.

I first tested this on the filtered water from my fridge. It measured around 300 PPM. I then measured the distilled water from my machine 5 PPM. I also measured some distilled water from the store which came in around 1 PPM. So I believe this item really works. One of the things I really like about this meter is that the display is nice and bright. Also the Meter comes with a case for storage, its not necessary but it is nice to have so that the Meter isn't just sitting out in the open.

Ron: Everything was packaged excellently. The instructions are very thorough and I did calibrate it even though it did come calibrated. I tested my pool pH when received and after I calibrated. The difference was 0.8ppm. I have used it each day now and this is so much more accurate and easier to know what the pH is than is the color orange or red or red/orange or orange/red. And should I read the paper strip at 15 seconds or 30 or before 60 seconds. etc. I also use it for our spa. If you have a pool or spa and you are having issues knowing whether the pH is 7.2 or 7.8 (and why do the test strips skip 7.5?) BUY THIS! My wife loves this too! Thank you for making this device!

Benjamin Massey: Its resolution is solid. It read exactly what I expected. And it has good buttons. Light up display. If it dies I will update. I used it to measure nutrients.
