I bought this about a month ago and it has paid for itself a few times over already. The cable it comes with is great. I recommend this for any drain tech or any service plumber. I had the old Ridgid Koffman power top snake and it finally quit working after 15 years and instead of repairing it I replaced it with the Ridgid self feeding K-45. Best $385 I have spent in a long time. I rarely have to use my hands to push the cable in. I'm sure other drain guys on here are very familiar with it and its self feeding benefits but I am still very impressed with it. I can easily make it down sanitary crosses for side by side lavs and thru 1-1/2" tub traps. I only wish I had bought this sooner.
