Works very well and highly recommend. Will pay for its self quickly if you go through canned air quickly.
This is really just a reverse vacuum aka a blower. You can use it to clean your car and whatever else as long as you don't blow dust back inside the interior/house/office. Like other people on this thread I emphasize the last part because this thing is pretty powerful. Solid, made in USA for people who care, and stays powerful upside down without canned air spraying out.
