This review is from: Omron M2 Classic Upper Arm Blood Pressure Monitor (Personal Care)
Got this for my mum as she needs to monitor her blood pressure. Seems to give results similar to those that her doctor gets (allowing for any variations that can happen). Easy and simple to use. The cuff may not be suitable for those with larger arms but for my mum it is ideal for giving an indiction of her blood pressure.
