81.8 Singer has a number of Heavy Duty sewing machines and the Singer 4423 is one of their middle of the road models. It is very fast at 1100 stitches per minute and is said to have a more powerful motor than most home machines.  Owners feel that it is fast, quiet and also sturdy but some folks indicate that it will not sew through thick material as easily as they expected.  [REF Singer Sewing Machine Reviews]

Consumer Insights
Those that purchased this machine feel that it is sturdy and is also good for beginners.  It comes with a number of good features but not so many as to be confusing.  It is relatively quiet and at top speed sews very fast (it is capable of 1100 stitches per minute).  There are a number of comments however that it is not really that “heavy-duty” and it struggles with sewing through thick material or several layers of average thickness material.  Although marketing materials for this machine indicate that it has a heavy duty motor that is 60% more powerful than conventional sewing machine motors.  Also some folks (not many but a few) experienced problems with the machine after the 90 day labor warranty and were disappointed that the problems were not covered.

PROS
- Simple interface and easy to operate
- Sturdy
- Fast
- Quiet
- Good automatic needle threader

CONS
- Struggles with multiple layers of fabric or thick fabric
- Limited 90 day warranty on belts, bulbs and attachments
