It's free of acetone, which is the first thing that I check for a nail polish remover. It works effectively to remove light color nail polish (Romance from Avon) that I'm wearing on my nails(Update: It did not remove dark color as effectively). It leaves a bit oil residue on nails however I do not mind at all. Most importantly, it does not have a harsh odor, thought it does have a slight plastic smell, but much much better than other removers. $4.99 for 177ml is pretty good for this bottle.
As I quickly search the internet for the reviews of this remover, I found the American pharmacy CVS also has an identical (except the brand) remover. I won't be surprised if they come from the same manufacturer. Hopefully other pharmacies will fellow the step to introduce this nail polish remover and make it more available everywhere.
