I use the Firefox extension. It works very well even with a weak internet connection. The only one so far.

Too slow for a VPN - often even unable to open web page, moreover to watch streeming videos. Very small limit of data. Browsec is more faster and have no traffic limit.

Too many connection issues with too many sites to earn a higher rating. I want to love it, but I don't. When it works, it'sgood, but it's too sporadic
