Works well. The first time I wrapped it around the threads only 3 times and a drop flowed out every 5-7 seconds. The next time I wrapped it 6 times and had a perfect fit without a single drop coming out. The tape can be torn by hand. Remember to slide the tape around the threads with your thumb before attempting to connect the shower head. Also, for best results, clean the threads on the pipe of any previous residue before applying the tape. My only concern is that I bought it because it was recommended. Not knowing anything about the sealing tape at the time, I ordered it. When I received the item I read a few words about 1/2 inch tape being the best size. After using it, I found it true. Half an inch of tape would be more than enough. 3/4 inch tape works the same way, but it leaves a lot of unused white tape on the pipe.
