I purchased the Singer 4423 Heavy Duty because I wanted a more powerful replacement for my older but reliable Singer sewing machine. I wanted to able to sew a variety of projects using denim, canvas, leather, or other heavy fabrics with better results than what I was currently getting. I liked the simple design and straightforward operation of the 4423. It has a good selection of stitches (both functional and decorative) and some other nice-to-have features like adjustable needle position, automatic threader, and the one-step button hole which I was especially excited about. The other “Heavy Duty” Singers don’t have these features.
When I started using it, the first thing I noticed was the less-than-stellar quality of some of the decorative stitches, but I figured that it wasn’t really a big deal because I do a lot of hand embroidery and don’t use those stitches that often. I decided to do a little “test project” on the machine: a zippered pouch with denim lining. The machine ran quickly and quietly on the pima cotton shell and putting the zipper in was a breeze. I was disappointed, however, with how poorly the machine handled the multiple layers of denim in the lining. It started knocking loudly and a few times stopped completely when sewing over a bulky seam, i.e. the feed dogs couldn’t pull the fabric through. I rethreaded the machine, adjusted the stitch length, tension, and anything else I could think of that would be cause for “operator error”. It didn’t help. I guess the machine just isn’t as powerful as they chalk it up to be.
I would recommend this machine as an excellent starter for a beginning seamstress. It’s a bit more substantial than most of the other “entry level” machines but still has those nice features I mentioned earlier without a very big price tag.
For anyone who wants a TRUE heavy duty machine…this is not for you. I would recommend upgrading to a non-heavy duty machine in a better brand. That is, if you can afford it. I ended up buying a machine that was twice the cost but performs twice as well too. 9 layers of denim, no problem! For me, it’s worth the investment.
Hope this helps!

I am an entry level sewer so I needed a machine that was reliable and could sew through a few layers of thick fabric. I found this machine at a great price and decided to go for it. I have not owned any other machines but I can say that this one did mostly everything i needed it too. However, I was doing a project with a 1/4″ layer of very light open cell foam, and as i was mid-sew the machine made a couple knocking sounds as was stated in the previous review. I rethreaded the machine, made some minor adjustments, and finished what I was sewing. I do not think I would try to sew anything excessivly thick again, but lukily that dosent affect my using this machine. overall, i like it and am happy with my purchase. I know that singer is a trusted compnay, that has been around for many years as well.
