Just got the RATS that I bought and the awesome shade of blue ones you send to the PD. Huge thanks for those. I threw one on really quick and tested it against my BP/ Pulse reader. Soon as the RAT was on, my pulse was history and no BP. So out of curiosity timed it against my CAT and SOF-T, no comparison. The guys on shift were impressed and now really think I'm strange. The RATS had faster circulation restriction and was easier to place than both of the others. It's a huge relief for me to have my guys outfitted with kit that works.
