Here's a link to the feedback:
...from medical perspective:
Those stolen minutes ? as delicious as they seem ? aren?t worth it because
you?re fragmenting what little extra sleep you?re getting, so it is of poor quality + the body needs some time to get you ready to wake up. When you let yourself go back to sleep, your body thinks, ?False alarm! I guess I didn?t need to do anything, because we?re not getting up after all,? and settles in. When that buzzer goes off a second time, your body and brain are taken by surprise, resulting in that groggy, fuzzy-headed feeling called sleep inertia. The more you snooze, the more confused your body and brain get (?So are we going back to sleep or not?!?), so you?ll probably feel more out of it even though you actually spent extra time in bed. What?s more, this type of sleep inertia can persist for up to two to four hours, research has found + if you're following a sleeping cycle (consistent sleeping and waking up times), snooze button messes up your cycle!

And from doers perspective, snooze button is behind being late for class, meeting, or whatever you've planned to do in the morning!!
