Unacceptable! I placed them as soon as I bought them on the electronic watch I have on the nightstand (oh my goodness! What consumption could it have ????), and they lasted a maximum of 24 hours! I thought, never mind, they are not charged as stated on the packaging. I charge them again and it's the same. I'm glad I bought 3 packages! What if I run out...

Although I don't have a point of comparison, I think it's fine. I have tried them on various devices and haven't encountered any issues. I would buy them again.

Quite good.. I put them on a mouse and keyboard, one on each.. they hold up quite well. I got them from a super market for 6.50 euros..!!!
