So, I just covered the issues with the free trial, and what it offers. But, my 2nd suggestion is, altho you discuss in depth why you don't offer certain things during the free trial, you don't say what's offered in place of what isn't.
So I would simply add to the info that while you may not offer "such and such" you offer __________ in it's place during the trial.
You also have no information on cost. I know you prob do have something written on another page when verifying your free trial, but it should be on the same page before you decide to do the free trial. One, that's a bit of a shady sales tactic, and 2. You'd get a lot more customers if you were straight up with everything someone would need in order to determine if a free trial, or paid membership is even worth it for them. If they can't afford it then I don't see the point. I hope you understand what I'm talking about, and if you have any questions, please contact me. Thank you! Sara
