It works well and provides seemingly accurate values. These are, however, were not matched with a physician, but are approximate to the doctor measurements. But the accuracy of the device is subject to an ISO standard, which paper technically accurate readings are guaranteed in a certain interval.
Furthermore is included with a set of batteries and the unit operates sparingly.
It also still has a DC power connector (not one-hold electric plug with, but not as bad batteries will last very well)
The device is restricted to essential functions, providing clarity. It measures systolic / diastolic and pulse. The clock can be left permanently ads ;-)
It also features an internal memory, which can show past readings.
Last but not least is also an extensive description available constructed very understandable.
The sphygmomanometer thus gets from me 5 stars, as well as the price / performance ratio is very good! :)
