This thing is awesome it just hogs the hell out of the dryer vent.  I turned my dryer on blowing cold air then took the auger brush and started going to town.  Some things I found out while researching this item that helped me

1.). Use a drill to help clean it out works way better than by hand alone

2.). Set cordless drill clutch to a low setting to prevent from breaking poles.  I have an 18 volt Ryobi and I set my clutch to 4.

3.). Never ever ever turn drill in counterclockwise direction unless you want to go fishing for disconnected poles.  Can duct tape joints in case you may forget
