Indeed the screws that hold the two panel (front and back) of the cooler are broken with the arrival of the product (half screws, the other held), so the grid above ventillo did not take (we can the back with a few tweaks, but not buy a product for the duty tinkering immediately).
The product being sold by amazon was well packed by them, but hung in its box manufacturer, so I think if you received it in one piece that you have been lucky.
But otherwise, it works, that's something, right?
