These ErgoDox EZ parts have been returned for various reasons, and have been decommissioned. They may have jittery, scratchy, or broken keyswitches, but most power on, and most keys output something. There is something wrong with each and every one of these units. Buy them for parts, to fix yourself, to hack on, or any other purpose, but know that these will not work perfectly out of the box. No keycaps are included.
There is NO WARRANTY OF ANY KIND on any of these parts, and they are not presented as fit for any particular purpose. Buy at your own risk - these will not be serviced or supported in any way by OLKB or ZSA Technology Labs (makers of the ErgoDox EZ).
33% of the proceeds from these sales go directly to QMK.
