I like them a lot, don’t pay full price as they seem to have “3 years for the price of one” offers pretty regularly (which often get mentioned via boingboing)
Very easy to use compared to rolling your own (Their mobile program is basically a nice easy interface for openvpn). Windows use is easy to set up and can be made automatic for non techy family members.
If one server gets blocked for some reason, just try another (and they have lots, all over the place).
Occasionally when using a server from the UK list, my youtube adverts will change to german or dutch, but thats the only negative comment I’ve got 🙂
Based in (I think) Peru? or somewhere else legally insulated from UK snooping. Which may be more important when UK Gov realises the the porn age ban thing is totally ineffective and outlaws vpns “for the children, you monster!”
