A simple-looking but clever and often very helpful little tool. It allows photo and video cameras (including action cameras) to be easily attached to table edges, window sills and all kinds of surfaces. Weighing only 257 grams, this extremely practical clamp can hold up to 6kg. This means it can support most camera models.
