Saves me every time
I dont really fax much. Just like 2-3 times a year. Mostly I go to kinkos which is expensive. And one time a year I have to fax documents. Like 100 pages!! EFax saves me time. Money. And its awesome!! I do get some spam. Not a lot. But I do get it. BUT because I have used other apps I can say this one is better than the ones I have used. Worth the money.
