This little gem has fixed GoPro's biggest downfall...not being able to see what you're shooting. Now with the LCD touch screen you can see exactly what you're looking at. Make sure you use one with your GoPro.
The GoPro Hero 3 has changed the POV game. The quality this little silver box puts out makes all other POV cameras seem archaic. You can grab screen shots off actual video that will have a higher resolution than most digital cameras. If you are into shooting POV do yourself a favor and don't waste your time on anything else.
