Product review (5 stars): Works as advertised
Bought this item based on reviews here and I am very satisfied. It performed as advertised and cleared up the problem. Very good value and fair price. One bit of advice. Insert one length of rod at a time. This is especially important with a vent pipe which takes sharp turns. When that length is all the way in, then attach the next rod to the last rods end still sticking out of the vent pipe. If you attach too long a length, it will twist up while outside the pipe.
