This wristband blood pressure monitor changes color when it detects an out-of-range reading. Readings are precise, and the wristband style is easy to wear and use. It's especially useful for those with hypertension and arrhythmia.

Readings in the 'good' range of pre-entered limits display in blue. Readings outside the targets turn the wristband blood pressure monitor's screen red. The color-changing wristband blood pressure monitor would be a great gift for someone who needs to monitor his or her blood pressure.
