Easy and straightforward interface. No trying to figure out how to convert to different formats as it does that for you. Easily editable as well. Great service!!!

It meets my needs very well. If I could get my own fax number for less than $10/month I would add that. As it is now, I have a fax separate from this but only pay $8/month so will keep and use separately. Disappointed it was so much for the add on. Also, for the edit option. Many things to do but all as add ons. For now, I like what I can do, though.
