I have only used on the initial setting which doesn't seem very powerful, but after that 15 minutes you feel it. Make sure the power cord is really in the machine because I thought mine was broken but you just have to push the power cord in pretty hard.
I just started using my vibration plate today. My first usage was a great experience. I like how smooth it feels and how quiet it sounds. The plate is very sturdy. The color purple is beautiful and vibrant ~ just as pictured on the website. I have read amazing testimonials and hope that I too will receive the benefits other speak about. I’ll be back to share more!
