They do clearly state in their manual that you should be heating the wire - not
the pad - and that you need to be careful to not damage the pad.

For my testing, I used some old, certainly not working boards.  I didn't have
any trouble desoldering things while keeping the pads intact.

I did have one mistake, but that wasn't in the desoldering process.  It was in
the removal process.  The desoldering tool cannot remove ALL the solder, so
there is a little left holding the component in.  Care is needed to make sure
that when you remove the component you don't pull the pad off because of the
residual solder.

Lesson learned: I still need to have a soldering iron near by to heat up the
area a bit to remove the component.  But the desoldering tool make removing
that component 100 times easier than with manual only tools.
