This makes application so much easier and you use less product.  It may take a couple of tries to get your technique down.  You need to hold the container up straight to keep the fibers in the bottom of the container and that way the air can circulate and pick them up to shoot them out the nozzle.  If I notice that fibers aren't coming I just give the bottom of the container a rap on my hand to knock the fibers back down to the bottom.  Once you get your technique down you will be happy.
