We have a 200' low slant sewer drain that has multiple curves with a 4' PVC. A few years ago we installed 3 drain outs so the plumbers could easily clear it out whenever it backed up. This time, I decided I was tired of paying $200+ every 2-3 years to have someone come out and do something I knew I could do myself if I had the machine.The machine worked great. After spending a few minutes with the instruction manual, I found it easy to use. It comes with everything you need to get started and to take care of a variety of scenarios. I first bored through the blockage which only took a few minutes. Then I attached more of a cleaning tool that took a few hours but I know I was able to clean out the pipe making it less likely to have to worry about it backing up for awhile. The plumbers that had come before never did anything but just make sure it was backed up and then they quit. The machine seems to have plenty of motor strength for the length of cable. It got stuck a couple of times but it was easy to back out and push through. I bought this one because it seemed to be the best value. It came with everything that I needed. It was a lot less then some and I am not going to need it that often. (It is not like I am a professional plumber who will be using it every day.) But even if I was using it daily, it seemed built to last overall.
