Yeah I prefer shiny and smooth condition but to shave my head that bald I need around 30 mins to shave and check and re-shave if needed. I sometime don't have hot water in the morning to get the best shave for new day.
As you said the skull shaver can't provide the result as close as razor shave, will the hair noticeable after shave?
And one more thing, the noise, I thought of using this while working, so is it really noisy?
