Decent system. Will get the job done and make your life easier in terms of the sanitization aspect: Clean, clear water (provided you balance pH, alkalinity, etc as is required with any sanitization system), feels nice, odor isn't really offensive, etc.
The only issue I have with this system - which is the same issue I have for all salt systems - is the cost of the unit vs the longevity. All salt systems I've seen on the market are great, time-saving, and pretty neat to have. Issue is - they only last a few years and cost several hundred dollars to replace, and that is *after* you've spent, say, $1000 or more to have it installed at the initial purchase.
If that sort of money doesn't scare you, your answer is self-evident.
But if that isn't something your interested in, I'd take the traditional approach vs adding a salt cell.
I hope this helps. Good luck moving forward.
