By adding a tough elastomer armor, Windmill created the Delta Shockproof Series, with all the stormproof qualities of Windmill's standard lighters plus incredible impact resistance for the most demanding conditions and most difficult outdoor challenges. Features Piezoelectric ignition technology - Piezoelectricity, now commonly used as igniters for gas stoves and outdoor grills, eliminates the need for batteries or flints which fail when wet. Releasing the lighter ignition button mechanically bends the lighter's piezoelectric crystal which produces an electric current.
Ignition occurs when an electric spark meets the butane gas in the combustion chamber. .
Shipped without butane fuel by law. . Manufacturing quality control - Each lighter is individually tested at the Windmill factory to assure the piezoelectric ignition system and the flame adjustment ring are working properly. Windmill provides a lifetime warranty against mechanical defects. The flame is more like a blow-torch than the flame of a standard lighter. The flame is very difficult to capture in a photograph as in the picture on the left.
