Timex ironman move x20 is the worst fitness band. allthough its light weighte super build quality. its overall a good activity tracker its track step, calories, distance covered, sleep track monitors, and gives a poop whenever any notification comes on the phone. overall its a good activity tracker but some how its lack behind from another competative fitness band like mi band 2, fastrack band, honour smart band and all another bands in this price segmant. the most contracy thing about this band is it does not have heart rate monitors thats an issue because all the bands in this segmant have that function. and the app which offers by timex is somehow improper in terms of calculating steps and messy its like a doodle puzzel when you opens it. overall I would not recommend this because another compitators are giving much more in this price range.
