The downside of pumps is that if anything goes wrong, your blood sugar can rise to dangerous levels very quickly, because you have no long-acting insulin. So they have to be able to tell you if there is a problem. Most pumps have a volume control I think, although turning such warnings off completely could potentially be dangerous. We’ve never had a total pump failure, cannulas seem to be the weak spot in the whole system (occlusions, leakages), but the pump also has to warn you if battery level is low, insulin running out etc, just in case you hadn’t noticed
