great to have an extra battery, helps out in sticky situations to be ready

An extra battery is a must have if you are out for the whole day. There's nothing worse than having your camera but the battery is dead and you have to resort to using your cell phone. It's just not the same.

Excellent batteries! a bit expensive but definitely worth the price.

Just what I needed, and after a few minutes to figure out how to get the battery in correctly it worked very nicely.

Excellent, no need to mess around with aftermarket batteries that may damage your camera.

A good battery with decent life. The BLS-1, BLS-5, and BLS-50 are compatible with my E-PM1 and E-M10, however, I now have to travel with two chargers as the BLS-1 can only be charged using the BCS-1, and the BLS-5 and BLS-50 can only be charged via the BCS-5. Although this is the newer model, I would advise to get the BLS-1 if you already have a camera that came with the BCS-1 charger, to avoid travelling with two chargers as I do.
