We started out with a USB a$$ blower a while back, now we have the USB optiwind mouse, the ideal Palmar Hyperhidrosis USB gadget. With over 28 CFM airflow those sweaty palms will never be wet again.
The USB optiwind mouse has a little more RPM than the USB seat blower we reported a while back (1500 rpm).
For the tech palmer hyperhidrosis type consider the 800 dpi, 25dBA noise level spec and MTFG of 20,000 POH.
The USB wind mouse is only $22.
