Never having used a serger before I was a bit anxious to sew with it. My fears were unfounded. The U-Tube videos and instruction booklets made it easy to begin. It took a few attempts to get all 4 threads threaded correctly but now it is easy.
                    The one area that was difficult was changing the needles out. I broke one and the area is very cramped to get 2 needles and stubby fingers in.
                    I still have alot of things to learn - how to use all functions- but am pleased with my serger A good valye for the money.
