This might be a good tool, but I had a very hard time trying to use it to clear a tough clog that was a bit far. Although it is long, it became hard to control the wire after a certain distance. My hands got sore trying to push it in, and it was hard to control the wire outside or inside the coil. Finally I gave up.A few days later I bought a "Cobra Products 650 Air Drain Blaster" form a nearby store. Although I saw it on Amazon I was not convinced of its effectiveness. But now that not much was left to try I bought it and it did the job much much much (I can go on forever) easier than this Cobra Metal Drain Clearing Drum Auger.
