Works really well
However, I would recommend not using it any more than twice a month as it seemed to cause white spots to develop in my nails when used more frequently. Can sometimes leave minor scratches on the nail surface as well. I don't know if I got a defective one, but I could swear the glass chipped on the sides. How that would've happened, I have no idea since it comes in its own case and was fine upon arrival.
