Summary: If you are getting this battery to have a spare in case you run out of juice using the genuine Panasonic battery, then it is ok. However, if you are buying to replace the genuine battery altogether, beware as it does not last nearly as long as the genuine battery.
Decent batteries, Good price. Hold a decent charge but will die out fast without notice as Battery indicator is not accurate.

Summary: OK batteries, Good price... Both batteries that came worked on my G7 and G6 M43 cameras. They seem to hold about 1h30 - 1h50min of continuous video recording in MF mode, which is a little less than OEM DMW-BLC12 Panasonic batteries. So they definitely are not 1600 mAh in terms of charge hold.
Excerpt: I recently purchased a new DMC-G5 from a private party. I did check actuation's prior to purchasing and it was indeed new. I opted for the G5 over the G6 because I have absolutely no need for wireless. Have you ever tried to send 100 pics to a laptop via wireless? It takes forever!.
Carry these batteries as back ups for picture taking trips.

Summary: Your camera will come with one battery. What do you do when it dies in the middle of taking pictures? What if you are on a vacation, away from home base, no way to recharge? Taking lots of flash pictures at night? Plan ahead and carry at least two extra batteries.
Inferior to OEM, dead in 7 months of light use, no web site for any support, stay away!

Summary: Don't waste your time or money on this item! Bought one back in June of this year and now some 7 or so months later, it will not hold a charge at all! It does feel lighter than the Panasonic OEM and while it worked initially, the charge was no where near as close to a used OEM one.
Summary: I couldn't be happier. The images are clean and sharp when used with the Sigma 30mm. I intend to buy a good wide angle lens for the camera and use it mostly for travel as I have DSLR's for event and portrait photography.
