Most of the information is only available with some code provided to individuals who have a
Rebismart, but I did gather that the medicine cartridge must be changed weekly, while the needle (hidden in a seperate unit??) must be changed daily. There are special care and maintenance steps which don't occur with the present Rebiject. And obviously, as the Rebismart is electronic, it will use up batteries or a/c power from a charging base of some sort.
