I ordered this product for its price (2.94 euros postage included), compared to a rate of about 6 or 7 euros in a jewelry store, it's no comparison ... Note that I received a Varta battery instead of this energizer battery operated, but there was no error on the reference (329) and after checking, the price of the battery I received is exactly the same on amazon, I am not disappointed at all. supplier would simply be out of stock for this brand.
