A must have is running Ozone

Installation and Operation Instillation was very simple this is a plug and play unit.
With ORP there is not calibration. It used a platinum probe that also cannot dry out and virtually lasts forever.
I used this in conjunction with my RedSea O# generator.
If you are running Ozone I highly suggest you use a controller or at least a ORP monitor.

Simple to use just set the desired OPR (425 for me with O3) and the controller does the rest. It's as simple as that.

Performance vs. Expectations This unit performed as good as expected. It did a great job controlling my O# generator and keeping my tank and family safe.

Value for money Pretty cheap as controllers go at about $100 I consider it a must have if running ozone.

Customer Support I never had any issues

Liked about it Simple to use set it and forget it.
No calibration need, ever
The probe will not dry out it could last forever.

Didn't like The only think I disliked about this was the set point is very sensitive.
Once the ORP reaches the desired lever is constantly on/off/on/off/on/off.
