I will recommend to use this extension if you are running a website which sells digital products. This extension has a full step by step user manual. I can say their customer support is the best. I am running my website in UK with PayPal UK. At the beginning, my PayPal configuration was wrong, so I couldn't get it to work. Then they just registered a UK PayPal account and told me how to change my PayPal settings. Now my business is running much smoothly because of this extension. I suggest to try it and you will love it.
