Largely I've been using this machine to sew face masks, surgeon's caps and isolation gowns for a local hospital during the COVID pandemic. This machine is a huge step up from my previous hand-me-down Bernina, which had rusted solid controls. I've been having a great time learning the settings on this Singer. The stitches are much tighter, controlled and stronger than with my previous machine. One thing I had to learn by experience is to tighten the thread around the circular knob before winding the bobbin. Otherwise the thread winds over and under the bobbin. The only reason for giving the machine 4 instead of 5 stars is that the motor smells hot when the machine has been used continuously for more than 15 minutes. It still functions perfectly, but I'm afraid of doing something bad to the machine by pushing it further when the smell is noticeable.
