Review on Green Label Micro Vacuum Attachment by David Magnus

I use it to clean keyboards, dryer vents and hard to reach corners where a more powerful vacuum would be useless. I was a little confused about the connector that reduces the vacuum cleaner tube to a small hose. It has a rotating vent which I thought should be closed for optimal performance. A little research has shown that the increase in suction power needs to be reduced as it increases significantly as the hose size decreases. Physics 101, which I barely passed. When you receive this product, my comment will be clear immediately. The packaging is smart and comes with a storage bag for parts.
