I recently bought a Sony a7 iii and wanted a spare battery. Tried buying in a lot of other places, but had issues. Finally I ordered on cameranu.nl and it came the next day. This battery has amazing capacity, so I don't really need a spare like I have with previous cameras. But I still wanted a spare just in case and I am so happy with it. I can put it in and do an awesome long time lapse and never worry about the battery. Yes, the orginal Sony batteries are more expensive than 3rd party batteries, but given how much I spent on the camera etc, saving €40 and risking it not working seems a weird priority...
