I installed FiOS in February. The techs that came to install it were great, the service is great when it works. I get 20MBPS down, 5MBPS up, as advertised. TV is not as easy to use as DirecTV, but close. I have 2 TiVos, and it works with them, but not using a serial control cable, so changing channels is slow.
HOWEVER, this weekend I encountered the first snag. My TV service went out on Friday, May 23 around noon. Despite 6 calls no one acknowledged the probem. A technician finally showed up 2 days later, and DID NOT FIX THE PROBLEM. Said it was in the network. But Network support says it is not. So I am currently (as I write this) in never-never land. The earliest a tech can come is Tuesday, 4 days after the outage. And I have little confidence that he will do any better job than the first tech.
