I use it with a small shop vacuum to remove dust from computer equipment. The storage bag is a nice addition. The brushes are extremely useful when combined with an airflow. I wouldn't rely on the airflow just to get rid of all the dust. Airflow is reduced as it is designed with air bypass holes to reduce the chance of your vacuum motor catching fire as it basically restricts vacuum flow when plugged in. The rubber hose is a little tight when cold and a bit awkward to handle. So far I have used compressed air in aerosol cans (Duster) which is specifically designed for cleaning electronics. More expensive, but definitely more powerful. I have a feeling that this tool will save me some money. If I could change one thing, a longer and softer hose. This hose looks like a regular low pressure water hose, like the one that connects to the kitchen sink, and can easily be extended.
