Good Value, Great Features, Easy To Use, High Quality

I have used a few different machines over the years and Singer has been my favorite brand! Then I got the Heavy Duty 4423... I love how I can push the pedal all the way down and it doesn't start bouncing around! I have had this machine for a couple of months now and I have nothing negative to say about it! This is a machine that I would definitely buy again!

Perfect Selection

I chose the 4423 because of its heavy duty construction. I make shoulder bags which have many thickness to be sewed together. The sewing arm was a surprise but a welcomed addition as I do a lot circular sewing. The auto needle threader was a gift from heaven. The brand name and warranty are all added pluses.

I sew almost every day, making shorts and dresses for children in Africa and Honduras (church project). This is my third SInger, and is very easy to use with quality construction.

Just bought this machine because my sewing/embroidery machine wasn't doing what I needed. I make costumes for my kids theatrical company and needed a tough machine that I could schlep to rehearsals and theaters on a weekly basis. The solid metal frame and basic stitches are all I need.
