Model USpicy Diamond Professional 24W I'm not a pro nail polish and I had never used a machine of this kind so far. After the hands and feet, I must say that I appreciate. The heat is very soft and pleasant, varnish dries much faster than leaving it in the open. This will lay the 2 layers of top coat colors plus protection without waiting between coats. We can resume normal activity as quickly and fits perfectly varnished. The UV / LED combination allows to be effective for all types of varnish, and low power consumption. The machine has 3 timers choice (20 ", 40", 60 "), but I used the longer each time, I found that fast anyway. The 50 1m power cord is long enough. I was surprised that the base is magnetized to the body of the machine, but ultimately, it allows cleaning and replacement easier. An instruction manual and a pretty nail file are provided, however there is no "recipe" on the art of asking the nail polish as professional, damage ;-)
