Offered Christmas is the 3rd time my wife uses it and a very white skin the result is already visible ... she is very happy, easy to use and not too heavy for a full session can last 2H . Only flat, all 10 flashes, he needs to recover a little to revive :) It is given for 5 years or 50,000 flashes (for 1 person), he looks well built (tough) and the small suitcase convenient for storage ... in 5 years we will surely do much better and I'll see the new brand.
