Nice gift, not very powerful though

I was given this as a gift, which I really appreciated, as I had always wanted to try a nail dryer. Claims to dry your nails in @ 2 minutes. If there's only 1 coat, and it's a fast drying polish, yes. I didn't find the cool air to be very strong. It runs on 2 not included AA batteries. My nails can still smudge after even 3 minutes. A hair dryer is more powerful.
