I'm impressed with the smaller footprint and weight compared the s3 and s2 which I've had. I doubt it will compare to the apple watch but so far so good.
I wish it was a bit bigger. I bought the 44m size....wish it was bigger still. It's a great watch though. I have had 2 Moto 360 and the S3 Frontier. Used S3 for 2years now ...love the active 2.
