Query: Died After One Hour of Light Use

I used this POS with the longest nails available. I was taking my time and lining up some moulding in between each shot. I drove approximately 15 nails. I used a yellow heavy gauge outdoor extension cord out of the garage where nothing else drew power. I lost the receipt but the store exchanged it for a new one. THAT new one died roughly the same way. Scared to buy a new gun. Don't know which one will live! I don't need it enough to go Pneumatic, you know?
