I purchased this smartwatch from ebay a few days ago. I bought a black steel 46mm model of the watch and it looks beautiful. There is a black steel band of very good quality which looks very nice. The watch runs on android wear 2.0 and has a heart rate sensor, pedometer, light sensor. The display is very bright and the touchscreen is responsive. The battery lasts for about 2 days. I can also track my physical activity with this watch using the modo body app which is a very nice feature. The only negative point about the watch is that it is very costly and I had to pay Rs 23000 for it.
If budget is not a problem, I would recommend this watch as it is the best smartwatch available.
