The best thing about this proxy is that it works with any device, whether you're using Windows or Mac OS X! It's easy to use as well; just plug in your computer/phone into one of its ports (USB included) an have at 'er!! There are some minor issues such as having multiple tabs open can be confusing when trying for something specific but other than those there isn't much I dislike so far - only because i'm still new to Smart Proxy :) If anyone has questions please feel free ask me anytime via their website chat system which will bring up my profile page where we'll talk directly through skype if needed :).
Using VPNs over public WiFi hotspots while traveling internationally makes browsing more difficult since most sites require cookies from certain countries etc., however once connected everything loads super fast again without lag like before connecting to wifi was causing problems previously.
