No frequent failures of NIBP here. Our units are old, purchased over 300 of them between 2015 and 2017 and some more after. Of the ones on this site (just under 50) I can only remember replacing one NIBP module since we've had them and that was under warranty. Internally no major issues from routine failure. The main problem we have with them is the rear case cracks along the top and under the flap covering the USB ports. These probably get replaced ever couple of years. The other issue is staff moving them around by the monitor handle and not the one of the trolley. We start to see cracks at the side of the handle. Some touch screens have gone. Checking the other sites out of just over 300 units since we have had them and out of warranty we have replaced 15 NIBP modules over the past 2 to 3 years
