The refurbished FR5 price is attractive, but the listing's inspected claim has no scope behind it. Before I pay for collection, what should identify the actual package, condition and support I'm buying for polymer-puck transfer? I can arrange a qualified assessment; I need to know what the seller already claims to have checked.
Ask for the identified arm, controller and included equipment, refurbishment work and inspection scope with findings. Then price any independent assessment and missing support before comparing that attractive total.
Their existing reply lists the arm serial and says motion checked, but doesn't identify the controller or describe the inspection conditions. No service history supplied either. That is the information gap behind my hesitation, not a fault I've found.
Keep collection uncommitted while those particulars are requested. Motion checked may describe a demonstration, not an assessment of condition or suitability for your complete puck-handling application.
