That thing works, just need a bit of setup but the details given on the page are pretty easy to follow. It might seem intimidating but you can try follow it step by step and it should work pretty nicely. Only down side that you can't specify the date range or a particular post. It will get every posts on a page.
As for his OF, I subbed to him like a year ago. It's hard to say if it's worth it because even if he has a lot of PPV but the trailers he posts are very long (like 5-10min long) that might very well be half the length of PPV minus the cumshot. So if you don't care about the "finish" so much and just want to see his huge dick in action then it's probably worth it. For me, I was subbed only for a month, maybe I will consider subbing again but not right now.
