I was with these guys for about 3 months, and it was only that long because they were kept telling me they were working on this and that, and all should be well "in a few days". Not to mention they gave me a free month or so when I bitched at the beginning.
They had the poorest completion of any pay Usenet service I've ever tried (Newsguy, Airnews, Giganews, Teranews, Usenetserver, and others I can't even remember). I think in three months I might have downloaded 10 files. And beware, cancellation is not an easy task. It took them a few weeks before responding to my cancellation request, and I've read reports of others needing to dispute the charges with their credit card companies in order to stop the billings.
