Ranked in these QuestionsQuestion Ranking
Pro The band is changeable, XL size is available

That gives it an edge over Fitbits, which are not waterproof). You can use it while showering, swimming, snorkeling and diving into open water.
Pro Plenty of notification functions
It can notify you of incoming emails, phone calls, text and calendar reminders from your phone. It has a function for setting and following team goals. It warns you by vibrating if it detects you have been inactive for a long period of time. It has a "find my phone" feature. It can read entire text messages and has horizontal and vertical screen orientation.
Pro It provides you with sleep metrics
This fitness tracker can also track the depth of your sleep, and it gets the exact time you fall asleep and wake spot-on.
Pro The charging port is also waterproofed
Most micro-USB or USB-C charging ports on waterproofed devices eventually develop leakage over the long term. This device has a propietary charging port, designed to ensure that the unit remains waterproof in the long run.
Pro It has a battery conservation function
To help conserve its battery, each time you are resting, your heart rate will be read every 5 minutes instead of every second.
Con The move notifications can get annoying
You can turn them off, but they will be on again after your established sleep time ends.
Con It has a hard time tracking stair steps
The unit has a barometric altimeter to help it track stair steps, but in some situations, it is just not accurate enough. For example, it sometimes gets triggered by elevators and other times it fails to count some stair steps.
Con Heart rate monitor often inaccurate
Heart rate should always be a linear progression up and a smooth movement down, and this specific model always shows some noise when compared to chest straps like the Polar H7. The noise stabilizes over a 3 mins time, meaning that the reads of both products will eventually be very close, but there is always bound to be some jumping around at first.
