I signed up a year ago, never was able to get everything figured out what I needed (5 IPs, for one), paid $80, never got it setup to work the way I needed. I asked them if they would be willing to try again to give me service for the amount I paid, they offered me 1/52nd of what I paid for. (a week) Whee! Yeah, no, Going to another company that can offer me what I need, and cheaper. For what I paid for them, I'd could get 5 years at another company.
No idea if their service works or not, couldn't get that far with it. I need it to run in a router (the dd-wrt router that is open source is what I want - so it can setup it to connect multiple machines easily without having a dedicated machine) - Needed this to replace my existing setup with Static IPs that I'm paying my ISP for.
