Mid-priced combos ($30–$70) typically draw 2–5 year service-life expectations from verified-purchase reviewers, with hose kinks and diverter o-rings being the common failure points. All-metal models like the Hibbent draw stronger longevity comments on r/BuyItForLife, while reviewers on r/askaplumber flag occasional internal leaks even on premium Delta units.
