This deceptively simple piece of kit was perfect for reaching an external seal from inside the house, saving a fortune in access equipment. Price per unit seemed a bit high initially but it is good quality and robust, which was important in getting a good finish. Out of the packet the joints were a bit stiff but assertive pressure got them moving and there was plenty of resistance to stop it moving about in use. Well worth having in the tool kit. A simple but genuinely useful item.
