My partner saw the commercial for the teeter and really wanted it for his back. So he ordered it and put it together and realized he couldn't use it because he had a rod in his leg. The ad never said this but placed it real tiny on the TV screen to consult your Dr. He never even thought about it. So I called to return and got the Return number RMA number and took to FX. It cost us 303.00 to return a 440.00 item. I was floored. Terrible company that say they guarantee it. They handled shipping and handling but later you learn that they only cover the ship to you. Don't order it. They are not totally honest. The man who took my order never told me this. User's recommendation: Don't order this! 303.00 to send it back is crazy.
