I was using these regularly. This is a set of two units. ● Challenge Pad 3 Main Unit ● Challenge Pad 3 Cover ● Challenge Pad 2 Main Unit ● AC Adapter ● Dedicated Pen Challenge Pad 2 has scratches on the screen. Please check the attached images. They are visible when the power is off, but the scratches are in an area that is not visible when the device is running. Both have been initialized. I would like to avoid spending time on negotiations, so please refrain from price negotiations. Thank you.
