I love this product that I use with my smartphone. And despite the weight and the consequent size of the latter, this support perfectly maintains that this is in use conventional tripod but also in the most scabrous positions, whether surpendu to a railing or wrapped around a pole!
It allows me to take pictures with angles of view imaginable ... Or just read my RSS feeds comfortably in the morning at breakfast.
An original product, but also very good. Easily removable and transportable, it now follows me almost everywhere.
