Hi there! I am thinking about getting the new (well, almost new) GoPro Hero 3 Black Edition. And I have two questions for people who own it already or might be knowledgable: 1. Are there any problems I should know about? The internet seems to be full of complaints about the battery life, camera freezes and other issues. How bad is it, really? 2. Are there any differences between the models sold in the US and in Europe? I know that e.g. camcorders sometimes have different framerates they record in (24p in the US vs. 25p in Europe etc.) and there might be other surprises. Because the camera is $400 in the US and 430 in Germany (which is about $580), so it's a lot more expensive here. And I would try to buy one in the US. Thanks for any help!
