I think in theory MIPS makes sense. But I didn't find it useful practice. First, the system created two bumps that dug into my head. I had to glue additional padding into the helmet to cover them. (Note: This was something that affected me. A teammate with a MIPS Synthe did not experience the same issue.)

My second complaint had to do with ventilation. The MIPS basically created a thin plastic shell inside the helmet that I felt made it hotter. It seemed to me that it trapped heat and provided a place for sweat to collect rather than to evaporate out of the helmet vents.

Also, I am looking to add a Protone to my collection in the near future. I don't care that it doesn't have MIPS.
I have a Synthe MIPS and crashed 3 days after i got it last November. I cracked the helmet and was able to still ride home.

Did having MIPS help.. it certainly didn't hurt. I got another using Giro's crash replacement and the LBS gave me a discount so I was out the door for $150 for the replacement.

I have 2000 miles and find it comfortable and the ventilation better than the previous Bontrager I had.

Reasons a manufacturer won't add MIPS:
1) License fees
2) It makes the helmet smaller if it's retrofitted. So if a medium used to fit, you might need a large.
