I haven't had this serger for too long, but after the initial trouble I had with trying to thread it I find it a breeze to use. I just couldn't get the threading right with the instructions so I went online and watched a video and now it take just minutes to rethread it.
                    I like the fact that I can use big spools or regular spools of thread and I like that I can use 3 or 4 spools. I would recommend this to everyone that is interested in purchasing this type of machine.
