This is what our happy clients have to say

I would like to let you know that I am very satisfied with this meter. I have been using the meter now for 2 months. The first two times, in consultation with my doctor, I compared the measurements of my home test (made on the same day) with the results from the doctor/laboratory. I was pleasantly surprised (my doctor too) about the results. The results were the same. I can now confidently measure my cholesterol at home and I don’t need to go to the hospital for that.


Professional meter and highly accurate measurement also at home. I am very happy with the test results as they correspond exactly to those from the lab via the GP. So I can confidently use this meter to monitor my cholesterol. Very glad I found this meter, saves me lots of time!
