Best accessory out there
This accessory is the best. It allows you to see where the heck you are filming. No more wondering if your helmet cam is only going to catch the ski or only catch your skis and ski boots. It also allows you to replay video if you want to, but the screen is so small it isn't really worth the battery life. I do think this shortens the battery life, but I think it is worth it. I would rather get a few high quality, well shot videos versus a lot of crappy ones.
