Product review (3 stars): Almost good enough
I like it, but it wasn't long enough to go form my laundry room to the outside vent.  That wasn't the problem.  I went to the outside vent to clean from that side also, but only got in about 2' before I hit a curve and the brush would not go past it.  No matter what I did, it wouldn't make the turn.  If I could have got past that turn, I could have cleaned the whole duct.
