    The pro's are many.

    The con's are:
    - slow throughput
    - delicate (tips always seem to break or collect residue)
    - resolution is limited by the radius of the tip end
    - ability to discern steep sample topography is limited by the tip aspect ratio and the tip end shape (flared tip can be better in this case)
    - tips are expensive!

    You have a good point.

    It is very easy to research what are the advantages of a particular technique. Google can be your friend. Or a library.

    The disadvantages of a technique are often hard to find or know. That's why I responded.
