Especially compared to small home nail-drying lamps, this device by Beautlinks works so well!! The space beneath the lamp is large enough to accomodate the whole hand and the light comes on automatically when you place your hand inside. It has timed settings for 30 seconds, 60 seconds and 99 seconds. It dries my gel polish quickly and flawlessly. I couldn't be more pleased! Thanks to Rank Booster, I was able to try this product at a promotional price.
