Quick review on my action camera iPhone case. So I was looking around at GoPros for awhile trying to find a suitable video camera to record some videos on the trail, but a decent GoPro with good options will run you somewhere over $250+. Did a little research and found the Optrix XD4 case for the iPhone 4s. Definitely worth the money, it makes your iPhone very competitive against a GoPro for about 1/3rd of the cost (paid $109 for the motorsports package). Check out the video below for a test run. If the video seems to lag, its your computer, not the phone. Runs smooth as anything on my phone but lags a little bit on my computer due to the high definition. Check it out!
You better hope that suction cup doesn't fall off with your phone on it. For what the new hero3 go pro can do I'd take that over using my phone. Plus if you get a good warranty through where you buy it you won't have to worry about it. versus your phone falling off and your buddy running over it.
