I had to replace my Hartman monitor that worked for many, many years but now developed a leak. Looked for Hartman in Canada and US but without luck. Decided to buy this Beuer. Looked nice, packed with features but the sleave is to short / tight for me. The readings were unrealistic for me but ok for my wife who has a smaller wrist. At the end, it is just sitting here, to late to return. I asked a friend to send me Hartman Veroval from EU; works fime.
