Review (2/5): Only good for a very light coat removal.
This is only good for a thin, light coat of clear nail polish. If you have real nail polish on it will fail to remove all but the sheeny top coat. The flimsy sponge does not provide enough pressure to remove a real manicure. The mouse is also too small to comfortably fit your hand, yet so wide that I spilled the nail polish remover inside (there are also no warnings on the container about the potential for spillage of the hazardous liquid). You can make your own by slitting a real sponge and sticking it in a bowl of acetone—it might actually do a better job than this.
