Upon receipt of the product, see if there are any holes in the box, bumps, or you see that the product has been manipulated in transport or any other anomaly, in case this is the case, you should ask the carrier to give you the "delivery slip" and write yourself on the paper: “Delivered with packaging in bad condition”. THIS IS VERY IMPORTANT!! Because, being a large product, the shipment is by truck and they work with CMR regulations and if you don't write this down, the insurance doesn't cover anything and they don't take responsibility, so we can't do anything either.
