Difficulty pairing the devices and syncing watch & phone - despite multiple soft restarts, placing watch & phone side by side or on top of each other, turning wifi on & off, toggling Bluetooth on & off. Seems like a LOT of work/troubleshooting to get devices to pair to provide information. If its the watch is the poorly-designed item, then I suggest you spend your time & hard-earned money on something else.
My primary reason for getting this particular watch/app was that I needed a fitness watch that could get wet, not have to worry about it getting fried, & have it read heart rate.
