Pros: Very low rates, good sound qualtity.
Cons: Sometimes takes a bit longer for the connection to be made, but it's a small price to pay for all the good I receive.
Summary: Was skeptical about changing from Ma-Bell to a long distance carrier who I knew nothing about, but the rates were too good to pass up. It's been 3 months now, and I have had plenty of time to 'sample" their service. If feels so good to have Ma-Bell begging me to come back...no way!
