So I've picked up a Moto 360 Sport as I don't fancy wearing my Huawei at a) the Gym and b) when out for a Run and I like it.
First up it looks nice, the silicone band is extremely comfortable and fits well and from first impressions should hopefully be very durable. It does however pick up anything off your clothes, kind of annoying but not a deal breaker.
Sadly the screen is nowhere near as good as the Huawei and the drop of resolution is noticeable but the screen is bright, autobrightness is nice to have and it does the job.
Was out for a run yesterday and the built in GPS impressed me a lot. Compared to my Microsoft Band 2 (which I'm now selling) it seemed to keep a very stable signal as the Band 2 would drop in the areas with plenty of foliage but the Sport managed to keep a solid signal the whole time as was proven on the route map from the Moto Body app.
The Heart Rate monitor worked well too which again is nice to see and the Moto Body app, while basic, can share your data with other apps such as Fitbit, Under Armour etc.
There is no general exercise option but there is an indoor run option which will at least try to track your treadmill distance and given it tracks your heart rate should give a decent reading of your calorie burn for a workout. I'll test this out tomorrow.
Overall I like it, it performs well but have yet to test it out properly in terms of battery life, this will be tested properly tomorrow. At the price it can be had for now, £139, it's certainly a good option.
