Feedback from my first several days!

A few bits of feedback. I'm extremely happy with my GoBe3 and I'm looking forward to future updates! My calories have been spot on but it seems my nutrients have been off, I also keep a nutrition diary and the watch is calculating that I'm eating almost double the carbs. I slightly miss having a couple of my smartwatch functions, primarily my timers and alarms. I use those to help with productivity at work (i.g. I need follow up at x time, I need to count breaths for 60 seconds, etc). I haven't gotten to have formal workouts yet with the GoBe3 but I see there is no where for me to specifically mark that time for a workout. With sleep I was accustomed to being told if I had light, deep, or REM sleep. I find that I'm less confused on my sleep with the percentage number, I do wonder there's a darker shaded bar in some spots on my sleep tracker at the bottom, what is that? I'm finding new functions as I go along and wear it longer, I'm sure a few things take a while to have enough metrics to use them. The weight loss goal function so far all I can see is it tells me what I want to do but doesn't give me feedback on if I'm on track or if my energy balance is off for my goals, maybe that'll come with more use?

I'm really excited I found this watch and can't wait to see what's in store for the future! One last thing, replacement bands would be nice, I'd like a dressier one and a few colors and I can't find extra chargers for sale on the website yet.
