FaxBetter is unique from the companies that you recommend. eFax requires a credit card in order to sign up for their free account. Then it only lasts 30 days. If you forget to cancel the account before the 30 days, they charge your card. FaxBetter does not require a credit card and is free for the life of your service and is advertising supported. The "rave reviews" are from users that prefer the FaxBetter method of providing a free fax service without the need for a credit card or cancelling before you get charged.
