Not bad but not great

Fast, effective & easy to use. Best VPN add-on I've found.

One of few VPNs that work in Iran.

Simply the best.

very good

One of the best solutions for anyone looking for a safe, fast and really well routed experience. There is no problem streaming or downloading. Your own ISP's speed is the only limiting factor! The user interface is simple and multiple IP changes can be accomplished in a click. Simply Brilliant.!

This is a great VPN for free.

i just love this vpn its strong even in free mode

The best VPN I have used. It always works.

Not only very stable and smoothly used compared with other service provider but also having excellent UX.

Excellent add on and easy to use for Mozilla users.
