Taking it out, though, has not been easy. I popped it in successfully twice with the 7-fold and once with the punch-down fold, but I find I can take it out only by inserting my index finger to form a shallow C-fold, gripping with thumb and middle finger, bearing down, wiggling the cup back and forth for a bit(pulling slightly all the while), then finally tugging it out. Did I mention that all this is done while squatting? Sure it takes me only 1minute at max, but I think it'll make for a royal mess if I'm bleeding!
Anyway, I've trimmed 3 mm or so off the stem, which has taken the "bite" off. I'm leaving it in overnight, let's see how things are in the morning!
