Anyone uses Perception Neuron + Facerig with Blender?

Hello everyone, I was wondering if anyone is using the Perception Neuron + Facerig package with Blender, and if so could you give us a quick review on it?

We are using Perception Neuron with blender, what are you wanting to know?

Thanks for the reply, I read that PN is a bit of a pain to use, very sensible to magnetic flux, is it true, is it usable, and how does it play with Blender, does it come with a decent software, was it a good buy?

Also, what rig do you use with it?
