Go read the reviews and then buy a real soldering tool.
Wellers and Hakkos are good. Metcal is REAL good.

I have one. It uses large currents to melt the solder. It sparks when
you touch it to metal. However, it doesn't have enough oomph for even
small soldering jobs. Also, there are warnings about using it on
'sensitive' electronics. I wouldn't recommend it.
It's crap. I like my butane soldering iron. Heats up quick and I can control
the temp.
Maybe you can't find anyone who has damaged components because anyone who
would be working with sensitive components wouldn't use the thing in the
first place.

I know a CE who defends "reviews" that claim ColdHeat is actually
better for 'sensitive' components. He relies on published reviews over
any user comments because he believes reviews are based on controlled
laboratory settings where the device is used properly rather than users
who may be misusing it.
It's unfortunate that most sensitive devices that would require very
delicate soldering in the first place are probably too expensive to
risk destroying in the name of researching the uslessness of something
the has the "As Shown on TV" label on it.
