securely packed with no damage at all. The operating manual being clear and simple making for set up quick and easy.
We do however find the fan noise somewhat excessive even set to a minimum, which does cause problems when placed in a bedroom enviroment. Given that everyone has a different perception of noise level disturbance that may not be the case for everyone. In all we highly recomend this robust Australian built product.
