This is, by far, my favourite plugin for Virt a Mate. I prefer it to the other emotion and breathing plugins because I find it gives a more realistic and controllable effect. It probably needs the user to play with the sliders a little more than the other plugins, but it's well worth it. For instance, I find the Look Adjustments/Max Smile default setting is too much for my models, so I move the slider from 1.0 to 0.6. Also, the initial setting for breathing is off; you have to go to Body Movement Settings and tick Adjust Chest to turn it on, but it really brings the model to life. Even her nipples get hard when your proximity arouses her, which is a nice touch!
