I had a very long time a heart rate monitor from Medion, but after years showed signs of wear and had to be replaced. After test reports and customer recessions I chose the product of a fairly well-known brand, but was not satisfied, because the pulse values were often unrealistic. In a second clock from another manufacturer, the problem occurred that they no pulse values indicated at me, but at another person it worked. Also this clock, I could not use. Test No. 3 with the IIS in 2014, however, is a complete success. The clock on my first run - except at the very beginning of running - constant pulse values that are also realistic in my experience. With the manual, I got along well. If you set one of the individual values, the clock, the theme is indeed by also. That the clock also has a great value for money, of course, is very pleasant. The chest strap I found purely visually somewhat narrow compared to other products, he wore but then when running normally.
