Bests & Worsts Reviews from Amazon

When using it I felt my muscle toning for sure, but I had to use it 5 times a week for an hour for about 3 weeks before noticing any improvements. But none of that matters now. The unit just flashes with an error everytime I try and use it now. It lasted maybe 3 months. I'm going to try and get a replacement, and I will update if I'm successful.
