My first impressions: Sturdy, heavy-weight piece of equipment. We haven't had much of a chance to explore the capabilities yet, but I did immediately try a low-level vibration session and I was pleasantly surprised at the effects: my knee (still recovering from a patellar dislocation) that has been aching for a couple of days felt less achy, and my neck that had been knotted and tense for weeks felt appreciable less painful. 2nd say I tried 5 minutes on platform with 4D active, followed by 10 minutes of vibration stretching. I'm being cautious because of my injury, but I am cautiously optimistic.
User friendly and easy to operate. Love the different training mode features and work outs. My first workout on it felt wonderful. It's now apart of my morning and night routine.
