After what I had read about battery-printing (other reviews) I found it hard myself to order these button cells. The choice was between brand cells or just this - to Camelion I researched, based in Germany, trustworthy. Hence my decision for it. However, when receiving the goods I had to realize that it is neither the depicted in the article description batteries nor ever Camelion; there are "Arcas" button cells, so ordered a completely different product than that. Unfortunately, I know nothing about this product concerning. Durability, or similar performance .; even if these batteries should come with the same design and the same actually ordered from the company, I find this approach unacceptable to send a product, which is different from the ordered.
