I bought 2 one for myself and one for my mom and we both love them!
I have been using this couple times a week for 10 minutes at a time. I have lost several inches off my waist and have been able to take off four of the notches. I love the fact that as I lose inches around my waist I can tell a big difference by removing the notches.
My goal is to use it everyday and go longer than the day before. You can listen to music and just enjoy it. I can tell a difference in my waistline already. You can't stop smiling while using it.
