Review on Smart Band SB501 by Tugamobi- Touch Screen Tracker with Heart Rate Monitor and 5 🏋️ ATM Water Resistance for Fitness Tracking, Step Counting, Calorie Counting, 14 Modes and Alarm Clock (Blue) by Russell Galbreath

I trust the monitor when it shows my heart is beating at 144 beats per minute after 15 minutes of rotation, but not when it suddenly drops to 60 beats per minute in seconds. (I don't think it's physiologically possible without sudden death.) It happens sequentially. Therefore, not only are your scores often wrong, but your workout summary is useless as well. It shows me how far I've walked, walked, or run, and its most reliable indicator is my sleep hours. If you want heart monitor functionality, you don't need a Tugamobi.
