One of the limits is that you can't choose where your downloads go. Also, there are now ads on the unpaid version, which I think weren't there before.
I grew to dislike the app after running into the limits/ads. It does work, but it feels cheap and unpolished. There's no way I'd ever buy one of the pricing plans. I just don't feel like I would be getting my money's worth, especially when I could just go through a more involved solution.
