I'm in the market for a H&N restraint device. My belt geometry doesn't conform to the requirements for HANS. (Their belt geometry requirements are pretty stringent. I wonder how many people using the HANS device have belt geometry that doesn't pass muster?) I instruct at PCA DE's and I'd like the device to easily go car to car with me. Pretty much leads me to the R3 and only the R3. To be truthful, I like the ISAAC concept better, but that won't go car to car with me. Anyway, I'd like to hear from R3 users in regards to comfort, ease of going from car to car, and, if you use a Chatterbox, is there interference between the device and the helmet mounted communicator box?

(Yes, I did search the archives. I didn't see much user feedback. Of course, trying to search for just "R3" does cause some problems.)

Thanks,
