It's hard to review this until I've used it for a while, but my initial impression is that it does make the body work out in new ways and does help. Not only that, but the construction is very strong. Thus a fine vibration plate (having never tried one prior to this one).
Since my lack of experience, I can only give it 4 stars until it's proved itself. I always think it's funny to ask for a review right when one gets an item, and has no time to really use it and, like me, have not compared it with any other.
