This teeter company is very tricky! They offered me a 30-day trial for $14.99 free shipping, and if I am not satisfied with the product, they will come to pick up the item from me. But be aware here is the trick: "Free shipping" is for them to send the product but if you want to return it, they will charge you! Because this is what they did to me. They are very dishonest!
Bottom Line: No, I would not recommend this to a friend
