Bought and used the 1/2" by 50' Cobra drain auger to snake our main house drain. It's cumbersome at 50' and takes a little elbow grease but it worked great. I would not buy this large one to snake out an indoor drain but it worked well on a larger pipe. Also, when I purchased this product it was 11.79 and I got free shipping when it was combined with another purchase. Because of the weight, I think it cost more to ship than the actual cost of the auger.
