Are smartwatches really useful and comfortable?

Got one, people.
Let's see how it works out. I'll share a review here after a month of using it.

At times i feel its addictive

I've been using the budget Xiaomi Smart Band 10 (less than 50 EUR) for several months, which is more like a fitness tracker. The areas where I get the most value are tracking my sleep, workout performance, and food-related allergies.

I used to wear one... I initially had one for being able to see messages, calls and emails while in the lab or mfg rooms, plus the cellular part was nice if i didn't want my phone on me. I grew tired of it though, and it got real spammy after awhile. Now I just wear it for workouts, and go analog for aesthetics.
