In this video I just showing the performance of the Opolar Air Duster and Vacuum, when it comes to clearing some dust from an old iMac that I had to take apart and I also show it's suction power, by vacuuming up some seeds as well. It actually performs quite well for a fan based system and even though it is not as powerful as some of the air cans, it does not suffer from getting cold and losing its blowing power, like most of the air blower cans will do.
