## Customer feedback

Those reported impressions are relevant for routine home monitoring, and the large backlit display and two-user memory align with those needs. Customer perceptions do not establish clinical accuracy, which remains a manufacturer claim.
- Positive themes: Customers describe the monitor as easy to use and readable, with some praising its large display.
- Positive themes: The supplied feedback also reports positive impressions of accuracy and value.
