Its no brainer that this is one of the best budget smartwatch currently available in the market.
One of the feature missing is the heart rate sensor.
Everything else is available in the watch which we get in higher end watches.
The battery life is decent. It runs about 1.5 to 2 days on a single charge which is quite impressive and also charges the watch in aboit 50-60 mins.
The display is good and bright and is visible under the sun. The touch is responsive and smooth.
The belt can be changed and we can buy the belt from our local watch stores.
I totally recommand this watch if your budget is limited.
If you can put some extra bucks in then I say go with some round smartwatch like moto 360 2nd gen and others like that.
