Seriously, how does one break a tip? Are you ramming the tip into concrete?? I've had my Cold Heat iron for almost a year now, and I have to say I'm quite impressed! I use NiMH batteries instead of regular batteries, because they have a higher amperage. I do carry a regular pencil iron because I think we can all agree northing beats the original!
I find the biggest complaint on the cold heat gun is the fact that no one knows how to properly use one! It takes some practice to get the split-style tip just right, but I can even do pc board work quite easily now that I use the thing a lot. (I am in the radio-repair business, fyi)
And I don't care what anyone says, the tip is still too hot to touch immediately after soldering something!
Anyways, just my input.
