I signed up for the free trial for Adobe. It was useful for some basic PDF management tasks, but hardly earth shattering. Definitely not worth the absolutely ridiculous monthly subscription fee. When I went to cancel I realised I had missed the cancellation window, and was hit with a £130 cancellation fee (50% of the rest of my subscription. Yes that's right, it would have cost £260 over 11 months for the ability to edit and merge PDF basically). Yes, I should have set a reminder about the end of the free trial date, but really I can't recommend the service as good value, and cancellation fees like this are just cynical ways of catching people out. So, one star.
