Cryogenic Frozen Rotors

I've done once before about 10 years ago on my e38 750IL and had much better brake life out of them and the pads (they lasted 80k+ miles - I sold the car before they needed to be changed).
I have S55 brakes in the front and S600 in the rears and all need to be replaced and my last set non treated lasted me about 60k miles.
After googling I came across this company which seems to have reasonable pricing:

Last time I did it from a company in Wisconsin. I actually drove there to drop and pick it up as I wanted to learn more about the process.
Any help appreciated!
