How long will the beta be free?
At least 5 weeks. Sometimes longer, depending on capacity.
When your beta chunk's time is up, we email you asking you to take a survey about the experience. At the end of the survey, you can choose to keep your chunk and begin paying for it or let it be shut down.Most places have introductory offers of a month free or super reduced price with money back guarantees on services that don't need a shake down.
Had I not been acting so compulsively after just waking up, I wouldn't have bothered for a pithy 5 week (possibly more...) free "beta". It's not worth taking the time to setup something on this account if it's just going to switch to traditional billing in 5 weeks, IMHO.
Sure, if you feel you were misled, and now you have to spend time to ditch the account before they bill you.
Remember what Tyler Durden says: "the things you own ... end up owning you".
It's also a bit disappointing as I'm in the UK.
