Pros: The tape is thick - it won't fall apart when you wrap it around the thread, especially at the edges of the thread. pretty sharp. The tightness is very good - not a drop escaped from the joint. A week ago I sealed the kitchen sink and shower head and they are both clean and dry. At 119 feet, the duct tape is more than enough to seal every pipe joint in my house. The tape is universal - suitable for connecting different materials. Plastic, steel, brass, etc. The seal between plastic and steel on my shower head is excellent. The tape does not slip when wrapping - there were no problems with that. The sealing process was smooth and easy. Cons: Haven't noticed that yet.
