I'm selling this ColorEyes labeled DTP-94 because I have both this puck and a Spyder3 device, and don't need both. I am physically disabled so frankly, it's a royal pain in the butt for me to do the extra black calibration step that X-Rite colorimeters require. This DTP-94 is extremely accurate and consistent. Less than a year old. Asking $100 USD shipped and PayPal. Shipping to CONUS only.
