I received the product before the date set for it that's fine. This is the opening of the bubble letter I became disillusioned: 1) the product received is not the same as ordered (2400mAh instead of 2300mAh batteries, but not in the same series). On this point, it's not a big deal but worth mentioning. 2) the package was already open! So nothing says that the batteries in the package are new.
I contacted the seller but he did not seem very conciliatory. So in the future I will avoid ordering home.
