Here's my take on the 360 Sport:
Hardware
It's not the sexiest watch, but it's supposed to be a fitness watch, so I give it a pass for that reason. The rubber strap is comfortable, but it accumulates lint. The screen is pretty nice, and it's easy to read outside. Interestingly, the ambient display is easier to read outside in direct sunlight than it is indoors. I don't mind the flat-tire, especially since I use a dark watch-face, and I think it's a worthwhile tradeoff for the light sensor.
Using it as a fitness device
It's great being able to run with the watch and not have to take my phone with me. I loaded up about 200 songs for when I'm running, and the standalone GPS locks on within 10 seconds and seems accurate (honestly, I think it's more accurate than my phone). I had an issue with my BT headphones having a lot of static while running, but I started wearing my watch on my right hand instead of my left hand (my BT headphones have the antenna on the right side) and this seems to have resolved the issue. I'm still looking for a good suggestion for a workout app for non-running activities like pushups and sit-ups that will sync to google fit. I prefer the Google Fit app to the Moto Body app, especially since I can display the Google Fit data on the watch face that I've been using. One weird thing I've noticed is that the Google Fit app and Moto Body app, even though I connected them, have different step-counts and calorie counts.
Using it as an Android Wear device
It's great getting notifications on my wrist and not having to pull my phone out. I do wish you could fine-tune which notifications buzz on your wrist, instead of it just mirroring what's on the phone. There is an option that lets you disable notifications on the watch for a given app, but I'd rather have a more fine-tuned option than that. The most fun thing about android wear is making custom watch-faces, and I've enjoyed trying out a bunch of them from the play store.
Other notes
- Battery-life seems fine. It lasts the day, even when I go running with it in GPS mode, and I don't mind charging it overnight
- It took forever to sync my music playlist to the watch. It seemed to only transfer when my watch wasn't charging and had over 80% battery left. I think it took about 4 days for it to sync.
- It doesn't seem to stay connected to WiFi at all. I basically can't use this functionality because of this issue. I usually have my phone with me anyway, so I can live with this, but I don't understand what the issue is.
- I wish there was a way to sync the latest episode of podcasts on the watch for when I go running. The podcast apps I use seem to not have this feature yet and only let you control podcasts on your phone, which defeats the purpose of not needing the phone when you go running.
Overall, I like the watch. I'm curious to see how Android Wear 2.0 improves the functionality.
