If you are selling digital goods, this PayPal plugin is a must because it keeps customers on your website by opening a popup window where they can pay. 
This reduces the likelihood of customers leaving during checkout. Unlike most PayPal website integerations that keep customers on your site, no security certificate (SSL) is required.
What makes this PayPal plugin different then others on the WordPress Repository is the level of security built into how the digital files are handled. 
Other plugins render the items URL on the webpage by using MD5 encryption. However the MD5 URL can be easily broken allowing anyone to get your item for free.
What this PayPal plugin does, is it creates a unique hexidecimal string at install. Then in combination with MD5 encrypts your digital products URL into a string capable of being decoded only by your website. This is medical grade encryption and makes obtaining the download URL nearly impossible.
