He didn’t have any problems, setting it up, and used it successfully.

I recommend this

This hands down does not read PH properly. Used it for three months and tried calibrating and it killed everything month after month.I trusted that a brand new meter wouldn't be the issue, so I spent three months changing all variables besides that.I can't believe Amazon is still allowing these to be sold.

The Product is just as advertised, no complaints

TDS not working properly

Super simple to use and very accurate.

Does not come with any instructions and therefore it's not very useful. Trying to figure out how to use it from other videos and it still does not make sense. Going to try test strips rather than computer testers.

Conceptually, this tool would have been a winner. The reality is this device just didn’t give accurate pH readings (checked against a strip and traditional liquid with reagents) and the chlorine always seemed consistently off. Still looking for a solid device at a reasonable price.
