Misrepresentation of functionality of medical finger device.
Through a German marketing company a finger Oximeter is advertised as measuring, with considerable accuracy, a device for measuring blood pressure, saturation oxygen level and heart rate. I was sceptical of the bp measuring aspect and challenged the company on this claim. They never responded and, therefore, I am deeply suspicious of their claims. I have never come across a finger gripping device that also measures blood pressure, especially with the accuracy claimed. My advice is to avoid this company’s product if you want to have an alternative way of measuring bp. Wrist bracelets are able to do this, but they are not cheap. Digging further into the manufacturer of the device exposes that they are Chinese: Cao County Zhuoke E-commerce Co., Ltd. You have been warned!
