Query: Melts the plastic and doesn't seal evenly

Do not waste your money with this.cheap product,you cant make a straight sealing line does not seal all the wayyou end up with sealed parts and parts that did not seal at all and make the plastic that is above the sealingline tear off.this would work better as a plastic cutter than a bag sealer.do not recommend at all. does not work as pictured.
