Bult made their helmets so simple that pretty much anyone could figure it out without an instruction book. You charge the battery with the USB cable and you're ready to go, with buttons to control your recording right on the side of the helmet. There's a good camera installed, with your videos all saved on the internal memory card. And, once you've recorded, all you have to do is plug it back into your computer with the USB cable and you're ready to play. No software is even necessary. It's such a smart idea that it will make you kick yourself that you didn't think of it. But you'll get over that pretty quickly when you get one and start recording. There’s a range of sizes to fit just about anyone. You're buying a safe, ventilated helmet up to industry standards but you're getting a whole lot more.
