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

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.

Does what it's made to do

Good Value, Easy To Use, High Quality

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.

I do basic rather simple sewing. I find this machine significantly more powerful, and significantly more controllable; and that is a very good combination. I believe what they say when they it is a workhorse that will last a long time. I also enjoy the 23 stitches; and for the sewing I now do I think they will be quite adequate. I prefer handling metal bobbins and think it would be an improvement if they could design this same kind of bobbin operation, only use metal bobbins. Metal bobbins do have holes in them so you can see how much thread is left. My last sewing machine also has a strong metal case, but not as strong a motor. And this much newer machine has new generations of making sewing easier. I think it is a good investment I couldn't resist.

Good Value, Great Features, Easy To Use, High Quality, Fast And Accurate!

Simple set up, versatile and just an all around great workhorse of a machine. Singer has never failed me. It has handled fabrics from the lightest weight to multiple layers of leather and denim and does so flawlessly. I have had it for over 2 years now and logged a lot of miles on it. No complaints!

Singer Heavy Duty 4423 REVIEW

Good Value, Great Features, Easy To Use, High Quality, Like No Other Home User Machine Out There!

I recently was given this machine as a gift. My family has always used Singer Machines so I was happy to see the name I have always known. When I setup my machine I put it through its paces right off the bat with sewing some denim fabric. I have used other machines and this has always been my go to fabric to test the machine's limits. In the past other machines have not met the standard and have not been able to perform as I would expect. This machine passed with flying colors. I has handled everything I have thrown at it without any problems and I can say Singer without a doubt is still top of line in quality and ease of use when it comes to their products. I am very satisfied with my machine and will always continue to use Singer as my first choice.
