I haven't heard of this one either. However you don't get much bang for your buck, that's a tiny bottle.
I'm a massive fan of car cleaning products which I use for all kinds of jobs away from my motor, this for example will do everything that your GooGone can do but you get masses more.
I know what u mean, it does seem to be the case often these days.
in the past I used wd40 to remove really stubborn stickers, it works really well (but of course there are probably some surfaces though where you probably shouldnt start spraying wd40 on)
