I have several devices tested, this is for me the best. The Aufpumpgeräusch is very quiet and not unpleasant. The air pressure in the cuff is automatically adjusted and is comparatively gentle. Very practical is the included, beige and unobtrusive case, in which the device fits very well - therefore it is not always open around and you have to not stuff the package even if you want to store it. Full points for it - I would buy it again.
