Should I get one for my husband?

As the title says, I’m wondering if I should get an ultra human ring for my husbands birthday coming up. He’s said in the past he’s wanted something similar something small that he could use to keep track of his sleep and stress levels, etc. he has an Apple Watch currently but only wears it during the day or for workouts. I’m conflicted between buying him the ring or a garmin watch, but I don’t think he’d wear that at night. Let me know your thoughts -specifically if you’re a man. I’d love to get your input.
