One Max model, one Core model. I'd really like to not sell separately because this way, BOTH units can use all the Max model's algorithms. You'd otherwise have to spend a bunch online to upgrade the Core to do that.
Both units have some schmutz on the faceplate and long ago had their rubber feet removed. Velcro stripped the serial numbers from the underside of one of 'em, but this is easily viewable on the box for the unit and on the unit itself by holding certain buttons during startup. They're fully functional nonetheless and include original packaging, PSUs, manuals etc.
Venmo/Zelle only, price firm, you pick up in First Hill.
