As has been mentioned, I've seen the most benefit from indoor installations. In 10 years I've met two customers who were able to detect that their ozonators had gone out based on water clarity (not counting the folks who notice the UV light has gone out). One was an indoor pool that immediately began to build up chloramines, the other was a hot tub that was being used with no other sanitation until I took it over.
Most ozonators, particularly CD units, are dead in three years. If they were any sort of panacea for water quality the demand from hot tub owners for replacements would be deafening. Instead, when informed that their ozonators are no longer working or are faulting, most opt to just disconnect the unit and carry on.
I have nothing against them. I think they make more of a difference than than most ionizers, UV sanitizers, etc. on the market, but the cost/benefit for standard outdoor pool installation just doesn't add up.
I also want to add that the circ pump in the Del units is a VERY small pump and while it is helpful for chemical purposes it does nothing for filtration or circulation and should not be factored into any turnover calculations. Not that anyone said it should, but just want to be clear.
