Cold Heat Soldering

I've seen these before on the boob tube and just came across it at ThinkGeek... The Cold Heat Soldering Iron. I'd been wondering if this was a load or not and finally looked up some reviews. There's one at PCMAG along with some photos of it in action. And here's a more in depth one at Moddershq.net. Reviews seem to be pretty much glowing for what it's meant to be used for.

So any of you guys have one or used one? Might be a handy tool for quicky solder jobs.

It's been discussed before

Shoulda figured! I didn't even bother searching because I usually read every topic on the board... must have missed that one!

I got one for X-mass as a cheep-o stocking stuffer.
It is a resistance iron that creates heat through passing high current across whatever you are trying to solder. The tip is split and you have to make contact to both sides to create heat. This would be deadly to any sensitive equipment if you were to bridge 2 leads.
The tip the give is called the chisel tip, think big and fat. They offer a smaller tip on their website.
I tried the whole trick of touching the tip right after soldering something, Yeah not a good idea, I'm sure it was better than touching a metal tip, but not by much. My wife gave me a dope slap after that.
