Good product for the price.
I have been using mine for three months now and after fiddling with it I get reletively accurate readings. setup is easy and readings are clear. PH works well. Salinity gets thrown around with temperature changes. No biggie if you know what to expect.
Very happy with my purchase.

easy to use
easy to use, delivered with calibration products, just 5 minutes after opening the box, your monitor is installed and ready to use
