Been using a HANS device for over a year now.
I looked very hard into other devices such as Hutchins, ISAAC and decided that each, including the HANS, had their individual drawbacks.
I chose the HANS as I thought it fit my needs best. Doesn't mean it is the best option for everyone. The common concerns about the HANS are lack of side impact protection and the shoulder straps sliding off the support part of the HANS device.
I decided I could address these issues. For the seat belt, I checked the way my shoulder straps are routed over my shoulders by the slots in my racing seat and they chaff against my neck, implying they are as close as possible and should do a fair job of staying on the HANS device.
For side impact protection, I plan on getting a kevlar racing seat which incorporates head side impact protection wings such as on the new Cobra Suzuka seat.
