Product review (5 stars): Great Product
Works great to clean out the dryer duct. I think the taping of the joints in unnecessary as long as you are careful with the drill and what direction you are going in, I accidentally went the wrong way a few times but nothing happened. It cleaned out my laundry duct well, you must go slow and steady and run the air to get the clumps out. Worked well around turns as well. Definitely worth the cost.
