As great as this specific machine may sound on paper, we do want to say that this may not be the right machine for you – There could always be a better option out there. Use this review to take a peek at its features and try to make an educated decision on whether this machine will be the right fit. We have compiled a detailed list of features, specifications, and feedback on this machine for you to use to make that informed decision.



When looking for a new sewing machine, you have to know what kind you are looking for. If you are looking for a machine that will last you a long time and is durable enough to withstand hours upon hours of sewing, then this Singer Heavy Duty 4423 might be the right choice for you.

The machine is easy to assemble because it comes with the needle in place already. The manual that it comes with allows you to easily do any other steps that are needed to get this machine ready to sew right away.


The 4423 has a description of its durability in the name… “heavy-duty”. It has a sturdy metal frame that allows for great stability when sewing and/or quilting. The metal frame, however, does not mean that it is going to be super heavy. It is actually less than 15 pounds.

Sewing Speed

According to Singer and other reviews and sewing enthusiasts who use this machine, it tops out at 1,100 stitches per minute, which is really good for a machine this size. It will make for faster times on almost all of your projects.

Built-in Stitches

This machine has 23 built-in stitches which is less than some other options that carry around the same price range but is still a good amount. The stitches include your basic stitches like straight and zig-zag, but they also come with a ton of other decorative options that can be used in any situation.


This machine comes with dials on the top of it that are labeled. The left dial adjusts the tension of the thread, the middle moves the needle position, while the right dial adjusts the width of the stitch.

The front of the machine features two more dials that are used to play around with the stitch length, and the bottom dial is to switch in between the different stitch styles.

Automatic Needle Threader

Many users say that this part of the machine can be quite confusing but we found that with a quick search on the internet, you can find plenty of useful tutorials on how to word this correctly. There are also instructions in the manual if you need to use that as well.


The machine is decently lit when sewing, but many users have found that if you are sewing in a dark area, you might need to look into another light source to see better when working on projects.

Extendable table

This machine has plenty of workspace, but the extendable table makes that statement even more true. It also has plenty of storage for different accessories like different feet, needles, bobbins, etc.

  • 15.5 x 6.2 x 12 in.

One of this machine’s biggest assets is the ability to work with thicker fabrics with no issues. Heavy-duty doesn’t just mean the design of the machine. This machine holds its own against tough fabrics like leather and denim.

The many dials on the machine that adjust both length and width make it so that the machine doesn’t just handle the thicker fabrics, but can also work without issue on thinner, less durable fabrics.

Many reviews say that you might run into some issues with some features on this specific product but we have a few solutions for those so you don’t have to worry. Sometimes the bobbin will rattle in the holder while sewing – to fix this SInger included some small felt that you can be put on the top of the bobbin to stop it from rattling. 

Another complaint was the storage, while it is a great thing to have when needing to “store” things it can sometimes get in the way. You can easily slide it off so that it is easier to work with hems or cuffs.

If you are new to sewing, this is not a bad machine to start on. The combination of the included manual and the abundance of youtube videos that can be used to help you get started will make for an enjoyable experience with this machine.

  • Manual and a ton of helpful internet videos
  • 1,100 SPM
  • Easy to use dials
  • Adjustable lengths and widths
  • Storage

Sample Customer Review… I bought this machine over 4 years ago as my starter sewing machine, and it’s still going strong. I’ve made 30 quilts, 20 purses, totes/bags, and about a dozen items of clothing. This machine is so versatile, I’ve been able to do everything I need to on it. It has never needed maintenance (aside from a little oil), and it is a very easy machine to set up and use. Overall, this is a great machine. It is one of my favorite purchases.

Is It Worth It?

The machine has plenty of reasons why it would make a great purchase for anyone either getting into sewing or just upgrading their current model. The price is great for what it offers. Advanced sewers should not shy away from looking into using this machine as either their daily machine or maybe a backup if things go wrong with their current ones.

The metal frame and tons of features that the machine comes with definitely make for a great deal. Sure, there are other options out there that might have more accessories or features, but at a price like this, it is tough to beat. 

Singer is a trusted and reliable brand that many sewers will say make the best machines in the business. The fact that they are such a sound and trustworthy machine and still come with that wonderful 25 year Singer warranty makes it hard for us not to recommend this machine to anyone we talk to.

The 4423 is, yes, heavy-duty, but also fairly lightweight making for a decently portable machine that you can move around the house, or even take on the road if needed.

The design of the machine is very simplistic and looks very nice in the home. Its square body combined with the round dials makes for a very nice look. The grey model with the red and white lettering and designs are a great touch as well.


We hope that this Singer Heavy Duty 4423 sewing machine review helped you either make a decision or narrow down your options for your next (or first) sewing machine. The reliability of a Singer product, combined with the price, the features, and the accessories make this a great purchase for almost anyone.

Don’t let the words “heavy duty” intimidate you from this machine. They are basically just used to imply that the machine can handle all types of fabrics while holding up over time. We hope that you can now make an informed decision to help you reach your sewing goals!
