I want to buy a kind of fitness equipment online, because it is too heavy, not including express delivery, only including consignment.

Consignment safety is safe, and there will be almost no loss, non-receipt, etc.

Generally, the equipment will not be damaged, because the seller of the delivery has fully packaged the equipment before delivery, and the packaging material is shockproof and pressure-resistant. If you are still worried, ask for more layers of packaging.
