As one can infer from the title of my review, I rate this product only for one reason: the many negative reviews, the ONLY apply to a particular merchant, the section of this good product pull down. I use these batteries in the 3D glasses from Panasonic. The first set of batteries (per glasses a button cell) has maintained good 5/6 months. This at more moderate use of glasses. I find a decent value; at least one receiving unit and the two "glasses" with power to be supplied. So I can issue a buy recommendation for this button cells. One should not be deterred by the average overall rating is. In conclusion, a brief discussion on the topic Product / Shop Rating: a review always relates only to the purchased product, never on the dealer. To evaluate this, there is a feedback option.
