I just wanted a basic machine. I do a little quilting, made over 100 face masks, baby quilts, towel bibs etc. When I try to go fast, the threading on top comes undone on the machine. If I just take it easy, it is fine. I like the see through bobbin and the needle threader. I always buy the cheaper, heavy duty Singers and they last me forever so that was one of the reasons I bought this one. If it would stay threaded, I would have no complaints at all.
