Redmark provided excellent service and the device was efficiently couriered. I would recommend Redmark.
Wellue is a brand of the Chinese company Viatom Technology; something that is not readily apparent on the Wellue webpage. Given this it does seem expensive (the device price is high across all websites) for a Chinese product and I am uncomfortable knowing my medical data that is collected using the app is being possibly stored in China.
