Good: The revised opening mechanism is now much easier to use with one hand, because you can lift the bracket by loosening the ratchet better on a protruding "nose".
Default: In theory one comes true to all ports and the μSD slot approach, but one needs to have a fairly long fingernails or tweezers to the memory card and then can change. Without external microphone and the Skeleton enclosure attenuates the sound sharply.
Mies: As unfortunately common in GoPro makes you wonder why so little plastic costs so much money.
Therefore, a star price deduction.
Update 12/06/14:
After a fall from the table below 1m on parquet floor of the closure strap is now broken - ??? Sorry, but that should such a case already endure !!! Pranks So the good quality, and revaluation to 2 stars because I would expect at the price that both the camera and housing survive something like that!
