This device is only suitable for wall mounting, there are no feet in and it can not be operated in the state. From the product description which is apparent not quite unequivocally, why here in plain text. For use with us, unfortunately, unsuitable.
The minimum distance for wall mounting also is 50 cm below and 70 cm above the unit and 40 cm each side, and which is perhaps useful to know.
The sidewalls are also more brown than gray. Is a matter of taste.
