Samsung Galaxy L310 44mm Smart Watch - 7 Green Color, Fitness Tracker with Heart Rate Monitor, Sleep Tracking, Waterproof for Running, Swimming & Outdoor Activities

I had to write this as there are lots of battery police. I have had Apple watches and earlier Samsung watches, this is quality and the battery is no worse, is actually marginally better and when you take into account that this is powerful fast and snappy with a great screen the battery is not bad at all, still a daily or two day charger but I expect that anyway.
