I tried out onlingo because of their free trial. Sure enough, I wasn't impressed and was very glad I only had to pay for shipping back and forth and not the entire $69.95. So I sent it back with the RMA number plastered in tall permenant marker numbers on multiple sides. Imagine my surprise when I was still charged the full $69.95 a few weeks later. When I called they say they never got it back and since I didn't pay the extra to require a signature I have no proof I mailed it so they won't refund the money.
After arguing for quite awhile they still would only to agree to refund $50 since they don't have the product.
Unless you know someone who has Onlingo and you really think you'll like it or are willing to pay the extra to send it in a way they can't deny recieving DON'T try this product.
