complete nonsense. I ignored the bad reviews but they are right. My Hakko has plenty of power but the tip still gets cold and gets stuck in the pads when working with the board. It can definitely ruin what you're working on. I tinned the tip myself as I did all my tips by coating it with solder then turning off the iron and letting it cool before using. After 15 minutes of use (after proper tinning), the tip is discolored and no longer works.
