🔁 Return Policy

• No returns or refunds. All items are sold As-Is.

• We provide up to 24 photos per listing, but this cannot cover every possible angle or detail. Only the conditions explicitly shown or described are guaranteed.

• Items may have other cosmetic wear, damage, or missing parts that are not visible in the photos.

• If you have a specific concern (e.g., probe tip, connectors, cables, sensors), please ask before purchase. We are happy to provide additional photos or details upon request.

• By purchasing without such a request, the buyer accepts that the item may have undisclosed issues consistent with second-hand, untested, or repair-condition equipment.
