I originally purchased separately the plastic 23 inch cleaner to unclog the shower drain. However that was not long enough and although something came out it only caused the drain to clog up completely. Desperate to fix the problem (since the water did not go down), I ordered this hoping the 40 inch would do the trick. It arrived the very same day (prime shipping). At first I struggled with it but after a couple of tries, figured out how to use it. You need to twist (turn) the coil by the handle once it’s inside the pipe. What it removed was horrifying and satisfying both at the same time. Finally the water runs down the drain like a dream! I bought the oxo drain protector as well to further protect the drain. I am so relieved! And totally recommend this product.
