I bought for At the Detailing our cars we thought the flexibility of the hose would allow it to get into hard to reach places and the layered straw would be great for getting into the air vents. To be honest it was more trouble than it was worth. Trying to figure out the best way to attach this thing to my vacuum with 3 different connectors was overkill and resulted in a serious drop in powder suction. It just doesn't work in my situation.
