I purchased a chew toy for my dog that was marketed as guaranteed tough but lasted less than 1 week. Dont be fooled by the 30-DAY 100% MONEY BACK GUARANTEE. If you are not satisfied because a product fails to perform as promised, which you will only find out after you/your pet uses it and it cannot be returned in the same condition that you received it, then you will only be offered a replacement. Not a refund. What is the point of getting a replacement that is not going to perform any better! And lets not forget that they will expect you to pay for postage to return it, and include a reply paid pack so that they can send the replacement to you.
