Security Kiss has been around awhile. I've used their Free edition on and off since 2009. Kiss Free edition is good for a short browse, but the longer you stay online, the more you risk the secure line being "dropped", and your data exposed.
That said, I tried their paid version a couple of years ago, and when the month was over, I went back to Free. I didn't see much difference in the quality. The only real difference was the quantity of country IPs available.
And, although there is a bigger variety of IP's available in the paid Kiss, they don't necessarily all work, any more than the free IP's necessarily all work at any particular time.
