I wish! Mine only came with one (as it should haha, after all, the box only has space for one...) lucky!
My biggest peeve now is that, charging it... IF you use the sleep tracking feature, then charging at night is not an option. And this thing takes a bit over 2 hours to charge completely, so not like you can leave it in the charger while showering and then go every two days. And I know you can use the phone to charge it if you have a Samsung one with inverse Wireless Charging, but still, takes forever and eventually you need to flip the phone to use it.
Having an extra charger would help like while sitting down at the office and stuff.
