HaywardHL-Chem Omni Logic Sense and Dispense

I have not gone through a whole summer yet but so far the CO bottle is lasting a long time and my pool hasn't been more clear with less work on my part.

Have had a Sense and Dispense for only two years; waiting on our second replacement unit as the case for the unit completely rusts out quickly despite being under an overhang

This sense unit really is a drag. After months of use I can never get the Ph to register correctly and the probes have to be cleaned almost monthly due to buildup that occurs on the bulbs. Really hard to get an accurate chlorine level measuring orp when it gets dirty so quickly. I think this is just a poor design. Definitely don't use it to dispense acid as the ph is always 10+
