Myself and my ex have this service. Her service is near flawless and saves money versus the ridiculous amounts Verizon charges for comparable services. Technical support is very good and responsive and local which means no foreign tech support. HOWEVER... my account has numerous issues with inconsistent service which is usually credited to Verizon's DSL lines. I have had numerous, lengthy problems with my phone and DSL service through PittsburghVoice aka Full Service Network. In my area the max speed for their top DSL plan is only 1.5 mbps which is barely enough for my needs .. and costs about $40 with fees. The phone is a reasonable solution for low call volume.
Pros: Tech support is their strength
Cons: Slow DSL, iffy customer service, hidden fees, annoying to deal with
