I like that it's an open source tool, which means we can customize to our needs without paying extra for premium features (which are needed in some cases).
If you're looking at this just from security standpoint then yes there could be better options out here but if your main concern lies with privacy concerns as well - go ahead! It gives us additional layer between ourselves & external parties while still allowing communication w/o giving away information about what services or resources i use internally- all within reason ;) There have been no problems so far when using PPP over Tor network :) Highly recommend taking advantage oF its Free version until end date comes around! The only negative thing would perhaps bEthe fact thAt they don't offer any way tO get paid account beyond free one after expiration period has come by yet!! But overall experience was very good :D.
