My main use: during outdoor sporting activities, more searching for endless minutes a discreet corner: a simple bush, a tree trunk is sufficient to urinate quietly and unobtrusively
big advantage: no need to crouch in the tall plants (or being stung by nettles) or to lower the pants in nature! and if it is good: zero splashing on legs!
very easy maintenance of a hand / no leakage even at a huge desire
trick: to predict 1 kleenex sessuyer easy to slip into the original box (the size of a box has doliprane UPSA)
secondary uses: WC not always very own cafe, public toilets in Paris (the advantage is that one can rinse immediately after use to wash hands of the bathroom)
I advice without hesitation, although cleaned zero odors in the purse or pocket;)
