Disappointed at the reception of the product. The product fit for purpose, that side no complaints, it ventilates and so far its engine holds the road (I use a second fan so it works just for me). As against the quality of the plastic used is poor, everything is fine, light, a little wobbly foot (not more than 1 foot price for a Christmas tree). So in the end, disappointed by the value for money even if the product was not unworthy as "to air" for now.
