## Before you buy

- Listing details are inconsistent: the title says 9.5 mm, while a special-feature field says 13 mm hardened steel. The chain specifications describe 9.5 mm manganese-steel links, but do not clarify what the 13 mm figure refers to. The combination is described as both five-digit and eight-digit, with different code-count wording. The product details also list U-shape form, Wi-Fi and app control despite the chain-lock description, and the stated dimensions do not match the listed 120 cm chain length. Confirm the selected listing's configuration, lock type and weight before buying.
