Chunky
inelegant design
hook-and-loop is impossible to manipulate without visual reference
No cherry-picked units sent by manufacturers
somewhat gimmicky

sometimes longer

no vibration for alerts or a silent alarm
the GPS consistently would lose signal
only two poor recordings

lack of additional metallic layer slightly reduced the profile as well
constant loss of GPS signal
impossible to change AM/PM using UP/DOWN keys
lack of steps on the watch home screen itself

record heart rate in the pool because of only having BlueTooth
