DNS leaks on every connection that I have tested via browser leaks.com. I can connect to some servers, but nothing works, not even their built-in Google test. Their privacy claims cannot be verified.
Yoga VPN has been available on both IOS both iPhone and iPad for over a year. So interesting this article was recently updated this year and still does not have accurate data. Love that it's free etc. but it's very slow! Takes an incredible amount of time to download 1 movie. It can work with Netflix, Amazon prime, etc. too (that also is not accurate above) but you have to keep checking different USA options to do so. Often the USA options labeled "stable" are not recognized by Prime or Netflix. When I use even the 3200 coins Fast USA VPN usually the sites recognize that I am using a VPN. So although I love the ease of use and the option to watch ads to 'pay' for use...it is just so slow that I am now looking into paid options.
Everything you would expect from a vpn server, and the great thing about it, it's very easy to use! Every dumbass can make it work! You can choose your level of encryption by earning points, these points are very easy to get, simply by turning a wheel of fortune, or watching an ad. The only downside, it does not support p2p (popcorn time) or bittorrent, they have a clear policy about that..
