I bought a V.I.O 1.0 when they were first released for just under $1000.00. I really liked the fact that it is almost waterproof and is supposed to be almost unbreakable. The best feature is the 110 degree wide angle lens built into a bullet camera. Being the size of my thumb and having an infinite amount of ways to mount it to yourself or your ride, it was my setup of choice over my previous GoPro Hero camera which I found too bulky to mount on a helmet. Mounting it to the top of my motocross, snowmobile and street helmets make for a nice vantage point without any blind spots when reviewing recorded footage. It also comes with a wireless remote (record and stop buttons) that attaches to your handlebars like a velcro strapped wristwatch. As for the recording unit, it's not really noticeable when I ride with it in my back pocket and the cable from the device to the bullet cam clips nicely to the back of your jacket. The microphone pickup is also in-line on the cable. I was using a 4GB storage card in the device set at maximum resolution and max frames per second, and hardly took the space I thought it would. Also,the Slednecks crew are still using these V.I.O. 1.0 for their series of movies, so they must be really tough. The price has dropped substantially since the 1.5 came out, and now as of today, they have a High Definition set that works and looks great. (Bought a demo unit before they were released) Picked it up for $400.00 and should hit the shelves for around $480.00. It is pricey compared to the GoPro. One drawback to using wide angle lenses is that upon reviewing your crazy footage of clearing 70 foot triples at the motocross track or going off a huge cliff on the snowmobile, it seems to flatten the perspective (makes mountains look like hills) and your friends calling bullshit on your numbers when watching what you thought were going to be your extreme videos. As for street usage, they work great, especially at the local 9 turn track.
