Overall it appears to be just another example of muddle-minded thinking by a company that wants to draw attention to itself.
Last year they were advertising unlimited, but in the small print there is a 60GB FUP. There were lots of complaints about it.
They run out of a tiny rented office building and have far more sales staff than technical staff. When I say sales, I mean telesales who cold call and there were several complaints of slamming phone lines last year and phoning up elderly people saying they were better and cheaper than BT, who then found themselves on inferior (not like-for-like) products.
Put anything bad on their Facebook wall and it will be deleted. I havent been watching for a while, but last year you would see several complaints in the evening, but they would all be gone in the morning. Haven't checked out their web-pages recently, but they were doing a lot of false advertising and inflating other ISP prices on their compare page.
They had very bad reviews on TrustPilot, but over the past year you will see lots of 5 star ratings all bunched together from unregistered users with names like Tom, Dick or Harry (no I'm not joking!) In fact I just looked and it still appears to be going on and theres even a post from someone who had pointed this out to TrustPilot fairly recently. You will also see that most negative reviews get put into dispute and removed.
The company itself has a history -
Search Russell Church & iTalk - its not good
So all-in-all I wouldn't really recommend anyone touch them with a barge pole. :/
