Here's an update on my experience. About two days in my feet began to get a bit drier and felt a little tight. By day four some slight lifting had begun. On day five full on peeling started. This has come in very thing layers so, while the skin it reveals is a lot softer, it is not over sensitive. While I haven't pulled or tugged, I have 'assisted' some pieces (that were dangling off my feet!). By day six (my first 'soaking' day) quite a lot of the peel had happened. Mostly on the less obviously thick areas. By day seven peeling began on my hard skin and now, on day eight (my second 'soaking' day), I can feel a tremendous difference in my feet. It has already been well worth the purchase. My feet haven't felt this smooth for years.
I will say that, if you get squeamish about these things, you probably don't want to buy it. And if you are a natural 'picker', you have to restrain yourself from pulling.
Also, it does come off by itself, so you will want a closed in shoe once the mega-peeling bit begins (either that or have someone follow you around with a vacuum cleaner!). I'm really looking forward to the rest of it coming off, so that I can begin moisturising again.
