So here I am at peace with the coin-cell entirely. I do not need many of those only in my pedometer. And here, the Camelion has already proven. It is no different from the more expensive batteries. The marking is good. As the shelf life will be from the coin cell is not in use, I'll see. But either way it is a very good ratio of price / performance.
Conclusion: From my side, there is nothing to complain about. Also shipping and shipping costs are 1A.
