When you do it, it’s just nasty.
I have never read off a teleprompter.
I actually have never had access to a teleprompter. When public speaking, I try to memorize enough to speak without notes. Sometimes I have notes, but I try no to use them. I think you are more likely to screw up if you have to depend on notes. Trump is an example. He projects and is a good public speaker, but when he has to read off something, it’s not as good. He should stick to his strengths.
