The app shows you the battery status of the case and each freebud. I loved the boot, except I have thin calves and that portion of the boot sticks away from my leg. So I tested the theory and had two other friends try it out. It looked to be in good condition and there was only one little scratch that would suggest it to be refurbished. I have contacted primos and will post an update on what they say. Pages and pages of the same stuff. I had a pair of these same shoes before and love them. Theyre super cute and super comfortable! They are super cute & Comfy! My only criticism is you have to memorize the position of the volume control because unless you are looking in a mirror it is hard to see controls.
