Having to monitor my blood pressure now while getting the right treatment for me is important. Being able to do it easily and conveniently reduces the effort to make this a habit. I can do this on either arm so it doesn't matter if you are left or right handed. The screen is clear. The cuff has a good range of fit. High blood pressure means any cuff will be very tight. Hold still and relax. It's sensor only goes as high as it needs. If your pressure is down it doesn't go up as high. A good product at a good price. Mid range for extras like memory of readings etc
