Yup, I got a MIPS helmet about a year ago (when I had a relatively minor crash on loose and rutted gravel down a hill while trying to avoid an oncoming car that wasn't as far over to their right as they could have been). Hoping I never have to test it, though. I will say that my previous non-MIPS helmet really did the job. It has a good dent and some cracking in the foam, but I didn't even have a headache.
