"I am very happy with the device I am glad I decided on my own and that gives me a security."

 I just bought a WIWE device under COWID. Since I already knew it from my friends, I bought it just as a precaution if I feel any measurable differences in my body. It was important to me that it also measures O2 color. Thank God my measurements so far show good values, I go to my cardiologist in early May, and then it is very good that I can show you based on the diary, and based on that I can discuss one or two of my questions specifically with my doctor.  I’m very happy with the device, I’m glad I chose my own, and that gives me a reassurance.  Best regards, Benke Hajni
