Over two years
This pair
$142
once - built to last about two years with normal care (the brand's own guidance).
Disposables
$120 to $288
over the same two years, at $5 to $12 a month - a commonly cited range.
A reusable pair only replaces disposables on the days you actually wear it, so your real saving depends on how often you reach for it. The more you do, the further a one-time $142 goes against a monthly cost. These are illustrative figures you can adjust, not a measured PeriodFinder number.

Is this one yours?
Sizing runs differently at every brand, and tier names do not mean the same thing twice. Both are one question away.
