After a Hörgeräteakuster had asked me for 6 batteries over 10 (I left the store without batteries), I searched the internet for appropriate batteries, which I also found to happiness. These batteries have a very good quality and they still are to hold by the end of 2017. I am so well looked after, because until then they have been used a long time. And 60 batteries for not even 19 are a real bargain. For me it is clear that I only these batteries will still buy.
