Very noisy from day one. USB ports worked well for about 4 months, and then they sputtered and died. The design does lift my gaming laptop to allow for better air circulation. It does not sit firmly on my desk; when pushed back, the rear leg folds up and drops the laptop smashing the USB hub in the rear.Item is used on a desk and is cleaned of dust weekly.Product would be improved if fan were quieter, foldable rear leg could be locked in place and USB ports were not in danger of bearing force of laptop falling when leg collapses.
