I haven't used this machine a lot yet, so I may update this review at a later time. The machine seems to be very nice and has several nice features. I've been sewing with very light-weight fabric, which seems to challenge the machine a bit. I've had to change needles & retread frequently to keep things from jamming. The instruction book is well-written & fairly thorough to giet me through the troubleshooting. I'm a little disappointed in the plastic piece that covers the bobbin case & allows you access to that internal area for brushing out lint accumulation. The cover seems pretty flimsy & vulnerable to breakage with minimal stress. All in all, I prefer this Brother to the Singer 90S, which I had to return because it jammed all the time.
