I'm about to buy a cheap one because I heard it can be useful in drawing, though nobody went into specifics.
But more importantly, I'm making this thread because I have a team graphic design project where we have to market an electric eraser, and are thinking about targeting illustrators/fine artists as opposed to the draftsmen these things are usually associated with.
I was wondering if I could get some testimonials as to the usefulness of this product to you or other people you know who use one. (We're specifically doing the small Staedtler battery-operated one, for its portability and low cost, but if you don't have that particular one, it's OK).
I saw it's a good tool for comics artists, so I'm guessing this could apply to other art involving graphite... How well? Can you render well with it, or is it only good for cleaning up unwanted lines?
Do you think electric erasers are underrated? Should more artists know about and use them?
