Have two of them adhered to a plate that I take as a base for my notebook, so that the fan does not soak in bed with lint. Keeps really well, both the adhesive and the feet of the notebook in the rounding of the rubber feet. Can the whole construction to 45 degree tilt in all directions, with no move that disk and notebook up to today. Another advantage is that the ground clearance of the fan gets even better fresh air sucked.
One point deduction for the strict rubber smell. But this has improved somewhat over the past 2 weeks.
