Primus Saver

I am looking to change my broadband supplier, purely for cost reasons. Has anyone any experience of Primus Saver? I can find no information about them, except on their web site, I've tried a search here but it had thrown up nothing, of course it is possible they are under another name. TIA

?
I just did a Search, set to All posts. Got several pages of results, many of which looked relevant. Especially the later pages, though I didn't read the threads, just the Subjects.
