Why it's buy-it-for-life
Redditors report cordless Waterpik units still working reliably after a decade of daily use, and describe the brand as consistently well-performing, though the battery-powered motor is noticeably weaker than wall-powered models — better suited for travel/backup use than as a primary replacement.

I believe Waterpik is the best when it comes to water flossers.
I bought a cordless one with a larger reservoir (not portable, just cordless) and really like it
I have an earlier version of this and it's at least 10 years old. Still works fine.
waterpik is a good brand. always performed well for me.
the battery powered one has so little oomph compared to the wall powered one
