I have several vpns on my iPhone and iPad since I find that sometimes one works better than another at a given location. One of those I also use on my PC successfully, VPN Unlimited. It allows you to select any global endpoint location if that is a benefit to you. I also got a great deal on a lifetime subscription :)
I would still look at on-line reviews as they may give you a better idea what features you might want to look for in your particular situation, even if the reviews are biased (sadly, some are).
