I'm kinda late to it
But yeah, it really does make those "too lazy to shave the last week" days significantly easier as opposed to just using a disposable.
That being said, at least in my case, you still need to do a once-over with a disposable afterwards to get a really close shave, but the electric still does most of the work beforehand.
i often don't shave for a week, but i need to get out of the habit because the shaver can still pull on the hair and that hurts. i did just order new heads/blades though so maybe that will help.
