If you intend to use your iPhone as your helmet camera to record airsoft action rather than get a dedicated helmet camera and considering the Mophie Outride Case, better read this review... "There's no question that the iPhone 4 and 4S both record above-average video, but the case's design prevents audio from joining the party. That means you'll need to think up an external microphone arrangement, or be content with overlaying an audio track atop whatever footage you cut together. The real killer, however, is the price. One may be willing to deal with those aforementioned nitpicks if the cost were low, and being able to utilize a camcorder that you already own certainly sounds intriguing. But at $150, it's just $50 less than the GoPro Hero3 White, which offers a far more compact package, a microSD expansion slot and bundled software for managing the clips.

The Outride is an interesting concept that proves remarkably compromised in real-world use. The thought of using a camera you already own to capture extreme sports footage sounds all too appealing... until you realize that camera is also your phone, your emailing machine and perhaps your lifeline in a pinch."
