Cons
Con Oversensitive pedometer overestimates your step count
The fitness tracker's step counter often counts movement unrelated to walking or running as steps. It ends up reporting more movement than has actually happened.
Con Hard to get the tapping right to active LED display
The double tap to activate the LED display lights must be the appropriate pressure and timing in order for it to work correctly. This can be frustrating to some users.
Con Watch bands are low quality and fairly unprofessional in appearance
The overall design makes it feel like there is confusion as to who the target market is for the tracker.
The watch face is sleek and professional in appearance, looking more like a regular watch than a tracker. However the bands available for the watch are made from a cheap-looking silicone. If you wish to buy a replacement band, they are only available in three bright colors (orange, plum, and teal).
Con Sometimes has issues with condensation inside the glass
The watch is supposed to be water resistant up to 50m. However some of the watches have loose backs which causes condensation to build inside the watch, especially after hot showers.
Con Difficult to read in poor lighting
The watch face doesn't have a backlight and the hands don't glow, so it's near impossible to read the time in dark settings without external light.
