Even people with sleep apnea don't know they are waking up multiple times an hour all night. You really have no clue how you're sleeping until you put it to the test.
Also, I don't think most people are in a position where they feel like they have amazing sleep every night. Yeah, maybe those people have nothing to gain from gadgets kind of like a person at ideal weight doesn't gain anything from counting calories: but what about the rest of us?
My wrist device was critical in helping me realize how few hours I was sleeping despite being in bed with my eyes closed for 8 hours.
