I have the Ghost now about 1 month in use (wakeboarding, water sports) The camera is without accessories up to 3 meters water resistant. Photos and filming work very well. Operation is easy to understand, the built-in display simplifies operation over a GoPro. You can immediately check the settings and possibly look at the pictures and videos the same. The WLAN function I rate possible as very positive (data transfer to iPad, iPhone or Android devices via Wi-Fi.
In summary, I would recommend this Action Camera buy immediately
