I received a 1.5oz sample of this product in the FEED gift set. The first time I used it, I was wearing a dark blue textured and be-sparkled nail polish, and I really thought I'd need to use acetone to get it off. But I wanted to give this a try, so I started with it. It took a bit of time on each nail, but the polish came completely off AND my nails weren't dried out afterwards. It left an oily residue until I finished and washed my hands that kept my nails feeling moisturized. I also used only one cotton round with the remover to get off the polish from both hands, without needing to add more remover or get a second cotton round - it really lasted and didn't diminish in effectiveness. Another pro: it didn't have a harsh, chemical scent; actually, it smelled pretty good.
I plan on purchasing a full sized bottle of this remover when my sample runs out. It's a really great product!
