I actually think it's a great idea for camping or whatnot (ya know when you are out in the woods & stuff.) A lot of time a portapotty isn't around and besides they are just... YUCK. As are most state park bathrooms.
And squatting in nature can be another adventure in and of it's own (meaning plants you might not want to accidentally bush with your back side; from poisonous to prickly.... and don't forget the creepy-crawlers; snakes, bugs, scorpions, or God forbid a bear......) I guess I am either paranoid enough or have enough survival instinct, I can see a distinct advantage of not being caught in that position.
Then again, this is a country gal's answer and not some "pillow princess."
(No jab meant if you are one, good for you.... I think... lol Nothing wrong with being pampered, but most of the time I GET IT IN! Whether it's from camping, mudding, messing with folks animals... Helping my peeps out with gardens... Hanging drywall lol)
I can see an advantage is being able to "do it like the men do." (WHich would be standing up! And yeah, writing my name in the snow.... a novel idea! Can we say "penis envy?")
My only hang-up is cleanup, unless I'm carrying it in a bag, in a bag, with a pack of clorox cleanup wipes... I can see it turning into something as unsanitary as a catheter bag... or a mini portable urinal.... yum.
And let's not even discuss thought of sharing one.... LOLOLOLOL
Yeah............
Maybe for a trip like I said, sure, why not.
An 8 hour drive through the dessert doesn't always guarantee a nice 4 or 5 star restroom to go in now does it? lol
I like to live in the real world & think realistically.
