I switched to unotelly after unlocator. It certainly seems much better, just more stable and reliable in general. It also has the ability to access two countries content at the same time, so if you are in Europe it is possible to see both UK and US content at the same time without switching settings. They also have a really handy android app for switching Netflix regions very quickly, giving you access to much more content than just US Netflix on it's own.
It's cheaper too.
