And found ... for about half the price I have 2 Battieren received (incl. Shipping).
Unwrapped .. inserted - and lo and behold: The scale goes again!
I was thrilled - even though I had expected this result.
For Design: The battery comes in a simple design therefore - probably in order to meet the standard, so nothing have the value for battery collectors on a special lens. Normal users should not care but that - because they're usually somewhere "built" is and will no longer be seen just to disposal.
Conclusion: Price is great !!!!
