Not returning core knit

I am going to upgrade to 5.0 after trial but want to keep my initial core knit. Just wondering what would be and how much I will be charged if i return just the sensor and the charger? They obviously cant resell it as it is not in a good condition already. So from a sustainability it would be better if whoop allows to keep it and use rather than dispose

Hi @anykeila,

You do not need to return your current strap when you upgrade to WHOOP 5.0. You can simply upgrade through the app and keep your existing strap. Hope this helps!
