I opted for this battery because the battery is factory sealed and will not be sent in blister, I personally have required the battery for my 3D shutter glasses and although this often is in use, the batteries should already now a very long time without to show signs of fatigue!. Even otherwise, the CR2032 is used in many things such as electronic clocks, card reader, calculator and so on. I can understand the battery only recommend because it really is a good product gets and this was sent quickly by mail, better not blister carded!, Myself is aware that one at the price loose a 5er Blister but gets the quality is of course correspondingly miserable and Here I spend no less than a few cents more than this one has also a long time what it.
