Mobius? When I get in I'm going to read the whole post I just read the first page and didn't realise there was 26 pages lol. So has the origional one you posted about turned out ok. I'll more than likely mount on helmet for convenience yes this camera i pretty good for the money. My only problem was that i wanted it to start recording as soon as the bike switched on, which required me to take it apart an monkey about with the electronics. This is the comparison photo showing the SportsDV alongside the Mobius. The Mobius is not waterproof - it needs a case to make it waterproof, so for all weather helmet cam action, the SportDV might be the way to go - although im not totally convinced the SportDV is watertight as it looks like it will leak around the buttons and lights. Ahh got you, well I would just have mine switched on as and when so the dv might be a good option. As for water tight I think I may be able to get around that although I would only be using it on rides out so chances of it seeing rain hopefully are slim, I doubt anyone would want to see my trip to work. The mobius looks tidy too. I should be getting one soon, I just can't justify a gopro for my use and doubt I'll start vlogging
