To be clear, these batteries are clearly inferior to the genuine Panasonic battery that came with my DMC-GF6. However, they work out to one-fifth the price. In my opinion, they are better than one-fifth as good. This was a good buy for me. I rarely use up the battery that came with the camera in a single day. However, these are nice to have as backups in case I do find myself with a fully discharged battery. On the other hand, if you find yourself often replacing the battery during the day, you might want to get the genuine Panasonic version. Another consideration is that cheap knock-off batteries have a reputation for having much shorter life spans. I haven't owned this battery long enough to comment on that.
