Purchased this as a groupon.  Bad idea.  I have to say my experience was exclusive to the scottsdale location.  I hope the other locations were better. \n\nMajor overcrowding.  Teacher seemed annoyed that so many people were there to the point where she didn't correct anyone's form and just chatted up the groupies. Two friends hurt their knees in these classes from lack of guidance on proper form. Customer service is non-existent.  The trainer wasn't very nice or pleasant, I am not paying for someone to be a jerk to me and also not train me properly.
