The accessories included in the winter package (eg Wrist Mount, div. Adhesive plates for helmets, fastening for ski goggles or a headband, Angle) are perfectly adequate for the. The lateral attachment to the goggle is however impractical. With the attachment, the angle and the body of the camera is then quite heavy and also wobbles considerably when driving. I have attached one of the included adhesive sheets directly on the helmet.
A small drawback is the recording feedback. As described, I have the camera on the head and start the recording with no view of the camera screen or LED. The camera makes sounds, but not for each action. The sounds are difficult to distinguish and under the helmet relatively quiet. I'd rather loud, less playful (a simple beeping: high = Start, low = stop) wish. Perhaps shoots Sony because after yet improved firmware.
