Product review (5 stars): YES!!!
This did just what we needed it to.  We had to buy two to be able to get the length of our dryer vent, so think about that when you buy.  We were able to connect the head to all the pipe pieces from both boxes to make it long enough.  Our dryer vent turns a 90 angle, it wouldn't make that turn, but the leaf blower took care of the rest of the blockage.  :)
