So without further ado, here's OPI Expert Touch:
A regular bottle that you would find at any beauty supply store is 120 mL or 4 Fl. oz and at Peninsula Beauty (where I usually get mine since Pure Beauty is almost always sold out) it costs me $5.99. Eeep. Oh well, if it does the job. I think at Beauty Land or whatever its called, the same size is $4.98 or something, so only a dollar savings. I don't mind paying more for nail polish remover, however, if it removes everything. In fact, at Pure Beauty I saw a huge gallon or something of this stuff for $25!! If I wasn't on a budget I would have got it. I still might, maybe if I see something like it at Sally's (which I need to visit by the way...).
My point is: When I was swatching those old Sinful polishes, I tried using a generic nail polish remover to save some of my OPI remover for when I really need it. I ended up using it anyway to clean up what the other remover failed to take off. I LOVE THIS STUFF. End of story.
