Device is super light weight, easy to understand the instructions. For 2weeks, I did it 3x each week. And although it takes time to be baby bum smooth, I noticed when my leg hair was growing back, it wasn't as thick or dark. Arm hair looked like my papa's. Have only just started on the arms, and can already see that it's taking a while for my hair to grow back. I love it. When I'm wide awake after my shower, I just plug it in and it just sort of kicks up the self care routine .
