I searched a long time camt Action and I admit I found my happiness with this camera at unbeatable value for money. The camera is tiny is additionally features an LCD control screen on the back, that do not have the GoPro to who can not help but compare it. For under 90 we are left with a camera filming in full HD with a rendering excelllente quality (wide angle 170 °). Delivered with a significant number of mounting accessories, waterproof case (not tested this), a rear screen replacement box, the helmet stickers, belts, cable etc ... impressive. By cons, a manual virtually nonexistent but is it really useful given the simplicity of the menus. This is not pejorative, they include all necessary options to a functional and effective use. It lacks a remote control to be on top. And frankly, by watching the videos, one wonders why pay more. Unless you want to use it in extreme conditions. FILES quality in terms of color, contrast and sharpness of the lens make this product an excellent choice. The battery is removable. I do not know if it is possible to procure spare easily but the range is very good. A little trick seen on the net for optimum tightening of fasteners. Spend a little bit of fine sandpaper in the joints of the dishes to ensure perfect contact between the different parts. The origination surfaces being a frozen appearance they tend to loosen with use. In short, I do not regret my purchase and I highly recommend this product.
