Works surprisingly good.
Works much better than soaking gel nails off.  Still have to leave mine in for about 15 minutes but most of the policy comes off in one piece after that if you work it off with the included tool.  May have to put a few fingers back in for a few minutes but works much better for me than soaking.  Less damage to nails. Only reason I gave it 4 stars is the indicator lights are a little hard to understand.
Rating: 4 stars
