I purchased it and honestly, I love it.
It doesn't squish for me and I tend to use it for pack and play. For STP without trousers it works perfectly. It's so easy and natural... but with them I am not perfect. Since I'm almost never willing to wet myself, I just use a stall. Still, I don't doubt that it would work just fine.
Aesthetics are good. Was discussing this with my boyfriend today. He thought it was cut but I pointed out that it looked like the foreskin was pulled back so the middle is a bit thicker than the rest. I don't think it's heavy and although I never really packed much before, I thought it was very easy to get used to and comfortable. I was also worried it would be too big--I'm 5"5 but it's not looked obscene or too noticeable.
Overall I am pleased as punch with the product. My boyfriend goes on about how realistic it is... but the wait time was more than x2 what the website suggested for me.
Can't say anything about the adhesion aspect though, sorry!
