This drain cleaner was easy to put together. The instructions were not that great but it was well made , heavy, sturdy quality design. I purchased this to clear my main drain line outside after having a terrible clog that previously cost me almost 300.00 every time a plummer came out. It took about 2 1/2 hours to unclog only because I didn't realize that the instructions say once you hit the trap/clog to put it in neutral. Figuring out that part was a bit confusing. Once we figured it out it took less than 3 minutes for the line to clear , clog was gone. I was recommended a 100 foot machine due to the length of my main line, by a very humble honest plummer after seeing I was frustrated and spending twice as much for 2 visits to my home. I'm glad I did! Now we can do this ourselves and save the money.
