Fitbit gen 1 is in fair shape and full functional. Does have signs of wear. The charger does work and as far as I know it does work with up to IPhone 14 Plus. Fitbit Versa 4 is in Great shape. It is brand new basically. I wore it for about a month and decided it really is not what I wanted. The only thing keeping it from being in brand new shape is a tiny dip/scratch where I tripped and it hit against the wall. Everything it came with is in the box.
