OP
Octopus
I had one of those. It worked for about 5 minutes, then I tried to use my computer with my internet connection and it never worked again. Vodafone said it could well be because it won't work with Virgin Media, so I chose Sky when I moved, but it didn't work with that either.
Vodafone blamed Sky, Sky blamed Vodafone, it looked like I was supposed to open some ports on my router, but I haven't got a degree in computer science, I was naively expecting it to work for any customer who bought it.
Vodafone said Sky would open the ports for me, Sky said they wouldn't because it would compromise security.
Eventually Vodafone decided it had broken after just a few minutes use, and since it was out of warranty I could either pay to get it fixed or fork out ÂŁ100 for another useless piece of their tat. Well fool me once, shame on you and all that, so I told them to shove their little flashing box of uselessness and their contract. After intimidating a few of their staff and belittling their useless ripoff excuse for a company on the internet, they gave me my fifty quid back.
Well... I've used it with Virgin and BT so no issues from my perspective!
