Query: Buyer beware...very poor quality

Normally I don't write reviews, but I felt obligated after using this product. After watching the video and reading the directions, I connected one of the 4ft rods to my drill and inserted into my dryer vent duct. After a minute, the rod snapped. Assuming the rod was defective, I used another and connected the other 2 rods. After a few minutes, the rod broke *again* and this time it was deep within the vent duct. It took several hours to fish out remaining pieces, which I promptly took back to the store. Please be aware, the quality of the rods are cheap plastic that can break very easily. I would highly recommend looking elsewhere and avoid the frustration.
