I had trouble installing it...and when I finally got it installed, I followed the info on the 'guide' tab in the component, and it wouldn't work...I had to mess about with some options and items, and finally got it to work with some PayPal buttons in a content item. But then, when testing it, it would only list the transactions that were done with a credit card at PayPal, not the PayPal account Payments...and then, it would not send the download link, and I couldn't get that code to work, so I could only send the document as a link on the email, but some of the files that people download from my site are too big to send by email, so that wouldn't work either. I tried contacting them twice, but I still have not gotten a reply or any help...so there is no way for me to try and get it working. So, in the end, I had to dump it from my site, and paid money for nothing. I wouldn't suggest getting it until they at least have some kind of support forum or better way to get support and help for it. It's just not intuitive for all in terms of getting it to work.
