The silicone cap for the housing is really top and already justifies buying :-) Nice Flexible and dibasic sees from (that would get me even 5 star)
The cap for use without a case is made of hard plastic and I have the problem that it pushes itself within a few seconds of the lens, vll is yes in Hero3 different, anyway. Silicone would be here probably the better material, but half bad, GoPro is anyway always in the housing
The Small cap is quite nice and also does its purpose, but unfortunately it is also hard plastic, which is why it can be difficult to solve because the plastic pins in the HDMI port of the camera slightly stuck. As a spare part but it is still very good.
Who can cope with this and just like me looking for a cheap cap for outdoor housing is the best advice here.
