Another thing about the GoPro that I forgot - the circular recording just did not work. It seemed to work OK if it was running when the card filled up, but if the card was already full when I turned it on, it just beeped and shut off, so the whole idea of just charging it up and using it is out the window, I had to manually format the card when it filled up, or hook it to a PC and delete content. I called support and again, they said that I must have crappy SD cards (with a heavily implied "because there certainly isn't anything wrong with OUR products). It still did this after I bought their recommended Sandisk Ultra card.

On the plus side, they do update firmware relatively frequently. On the minus side, they need to.
