Very very old cheap-make fitbit type tracker (Dodleston CH4)

I can't recall whether it stopped working or I just wasn't appreciating it it's many years since I last used it perhaps not worth anybody trying but just in case anybody would like to try: there is the device and two straps and the charger. It was for use with my Android phone. But I'm not holding out much hope that it'll work any more.
Collection from Dodleston thank you.
