Although that's certainly better than nothing, it's really not the full deal at all. Even the squatty-potty which is way beyond just tip-toes is only about half-squatting. I've compared and the full squat is the real deal.

People who want to do it (even in prep for a China trip) better work on simply spending time squatting in general. Apparently, westerners with sit-toilets actually lose the flexibility to do a relaxed, flat-footed squat at all.
