Still needs some work. By Douglas on 8/2/2017

This probe is pretty much awesome when it works, BUT some many other devices in my setup will interfere with the readings that if I ever move my wiring it usually throws my readings off and I have to calibrate or move the probe wiring somewhere else.
I can't really say that I trust this probe enough to ever actually believe the reading.
I just wish they could somehow shield the cable from interference.
Highly recommended if you're running an APEX! By FLSharkvictim on 7/24/2017

I am not sure the two bad reviews about the PM2 module but it's my favorite. I have a second PH, and a salinity probe. In order for it to work the proper way, you have to calibrate it and clean the probes with two part every 3 months. If you don't well then it might leave a review like the two above. My Salinity monitor probe is dead on to what my refractometer reads. I am getting ready to buy a 2nd PM2 mod for my saltwater mixing station.
Probe Stopped Working By Jason on 1/16/2017

While expensive for the module and probe it is nice to have a read out of the saltwater status. Can setup an alert if the reading goes outside your defined range. Probe stopped working after about a year.

A waste of money. Is never accurate according to my refractometer. Don't waste your money.

If you are 2nd guessing the PM2, don't. Just buy it
The conductivity reading from this module is dead accurate, and has a very fast refresh interval. This is a must have for the "control freak" the conductivity data graphs alone will shock the non ATO system keepers. Which now happens to be next on my list.
