The whole construction is quite shaky, the walls are made of deformable plastic. a camera with a different focus as a center, ensures that bend the lid of egg timer to the side and thus no drift is possible.
I can use the egg timer with a Gopro. My slightly larger Kompaktcam with pulled-out lens will still rotate, but the image tends already strongly downwards. With an SLR, you can forget this drift holder, too heavy!
Therefore, return is at Amazon.
