The Asus zenwatch 3 is highly compatible with many smart watches which are trending now.Its mainly because of its unique features.The watch is covered with a gently curved corning gorilla glass and thus protect it from small scratches.I was gifted this watch 2 months before by my uncle and I am carrying it along whenever I go outside my home.Another feature of this watch is its high speed charging with a battery of 340 mah.The 512 mb ram and an internal memory of 4 gb is apt for the watch.It has got IP67 water resistance which is one of the factors which makes it compatible with other smart watches.For users who are not satisfied with the 340mah battery, an additional 200 mah can be added by fixing an external part to the back of the watch.I have already fixed the same on mine.So as a whole I like this watch very much and is completely satisfied with it.
