Honestly I wonder why they created a mini one! To my the lush is so tiny compared to the Gravity! Its far less intense but more intense in the vibration. I think the gravity has 75% of the same buzz as the lush 4. I like that its small for convience and can sit in it unlike the gravity. Only thing I wish the width was wider, I have some issues with it and have to told it in place. For something I was longing for thats the part that let me down. Ya i give it 8/10 Gravity gets a solid 10 for 10!
