Came very quickly as promised. It’s definitely authentic and I registered the product successfully with the app. I have a Luna 2 and now upgrading to Luna 3. For the Luna 3, it will switch off by itself when in cleansing mode. But I always finish cleansing before it stops and have to hold the button for 5s to power it off (on this I prefer the Luna 2 as it’s easy to power on and off whenever U desire)
