I'm selling the home base, as I don't need it, though I purchased it as a set. I haven't updated the software since I haven't used it. As a bonus, I'll include the Catlog 1st generation main unit and a size S belt that I was using. This is just a bonus, so I won't discount the price if you don't need it. I was using it until recently, so I've confirmed it's working and have erased the device data. There are significant bite marks, so it's recommended for those who want to try it out.
