Ooh watched an AutoPulse one!
AutoPulse looks almost Star Trek. Very sleek and usable. It looks so unassuming when they pull it out, then it makes that chest COMPRESS. I'm aware that you have to press hard enough to get the ribcage moving, but I was not prepared for such an unassuming device to have that much force. I can see them slipping a vest onto someone in star trek that pumps their heart and helps carry them to sick bay.
Lucas is more star wars. It looks like a rib cracker.
So I think I'd prefer an auto pulse XD
And how did they get so freaking cheap?
