Heat Gun Useless

Hi ive bought a few of your tools and really brilliant in terms of price and quality. Only issue is the heater gun that actually serves no purpose whatsoever it actually lays here and i may as well throw it away. Just in the back of my bakkie and never use it for my electrical heat shrink applications i rather use my electrical heat gun. I understand a battery will never compare with 230VAC but rather take the heat gun off the market!
