Received this for Christmas and although it is fairly pricey, I cannot imagine my life without it! It was an upgrade from the super small version I had and this has just completely changed my skin care game! Used to help cleanse my face, the vibrations help stimulate blood flow to my skin in the mornings to remove puffiness (I'm a cheek sleeper, so this is important!) and re-stimulate my blood flow in the evening before bed.
I use the app accompanied with the product to set the duration of the vibrations when I decide to turn on the product. Once I do this once, I don't have to worry about the app and just continue doing my thing! Don't forget to use this on your jawline and upwards on your neck - made such a difference!
