Piperl4

I can attest to the fact they work my wife and I were stopped at a light when a guy going about 45 mph hit us directly from behind. We both suffer injuries but the headrest deployed and saved our necks from being broken. We are now trying to find out from dodge at what energy level a car that weighs a certain amount takes to deploy them. My wife was the first one to notice that they had deployed. So I for one am a big fan of them now.
