much better contact with the skin as WearLink

I had the Polar WearLink sensor two years in use. Disturbing was as eternal moisturize so that the contact between the skin and strap work. Only when the tissue was soaked in sweat, there were reliable contact. This became worse and worse over time, so it was sometime unbearable and I have replaced the belt. Now, the new sensor is rubberized on the contact surfaces and thus fuktioniert much better. A clear progress and therefore the good rating. The durability remains to be seen.
