I relied on the rave reviews from buyers and I am absolutely not disappointed. My 15 year old son never leaves his "lair" and my 13 year old daughter wants one. So I'll let myself be tempted by the purchase of a second closed eyes. For my part, I put strips 7 (3.50 m) in 2 hours 30 minutes, taking my time. Matched with a light gray metallic paper, the effect is fabulous. And friends like to try ... Thanks for the promotion!
