This really is one of the best watches, if not the best, that I ever owned. The battery quite literally lasts all week and often times longer. There is no other digital watch that can even compete on the battery life, sorry Apple, and the Google watch isn't even on the playing field in comparison... I mean it, I can use my watch for my daily runs for a week, 7 days, and it doesn't need a charge in between. I let it charge overnight after a week and it's fully charged ready to go again.The material and glass is very hardy and resistant to scratching. I often bang my wrist into the sides of the door or on the table and this thing is durable.The sensors are top quality and very accurately counts steps, heart rate and distance. Garmin has outdone themselves with this model. For the price it is absolutely worth it.
