Received mine today and after the first use I am so impressed has made my skin feel and look amazing in just 90 seconds I love sheet masks but the time they take isn't viable so this is perfect. Was a bit weary as the masks' themselves are a little pricey but I will try cutting up other masks to fit don't see why you can't! The app hasn't launched yet but still managed to use it no problem. This along with my Luna play 2 are an amazing combination highly recommend
