Great little workhorse!
To begin, I snagged a fantastic deal for this machine. In total it was less than 140.00, delivered. That is a great price, especially for one of Singer's most reliable machines. I have been sewing for a LONG time...over 50 years, since I was just a kid, really. However, this is my first Singer, shockingly enough. This is also the first sewing machine that has given perfect stitches and smooth operation from the first moment I threaded it and started sewing with it. I'm delighted with this machine and look forward to using it until I'm too old to sew!

Perfect Workhorse for My Small Business!
I absolutely love my Singer Heavy Duty 4423! My sister and I bought one each and they arrived in just a couple days. As someone who sews for a small business, speed and reliability are everything—and this machine delivers both. The high-speed stitching helps me get more done in less time, which makes a real difference in productivity. It handles heavy materials beautifully—no hesitation at all with multiple layers of canvas or even faux leather. The motor has impressive power, and I’ve never had to fight with the fabric. I also really appreciate the extra lift on the presser foot—it’s such a small detail, but it makes positioning thick fabrics so much easier. Overall, this machine has exceeded my expectations. It’s sturdy, fast, and efficient—exactly what I needed. No regrets whatsoever! Highly recommend it to anyone who works with heavier fabrics or just wants a reliable, high-performing sewing machine.

Works great
Bought this sewing machine for my wife in 2017. Still going strong!! She loves it. Very easy to use. Stitch quality is good. The bobbin winder stopped working so I bought a cheap bobbin winder that took it's place. Other than that, it works flawlessly

A Good Basic Machine...
I bought this machine because I had an older Singer Sonata (looks like it may have come out in the 80's) that was acting up. It seemed like it was time to replace or repair it. Sadly, repairs would've cost $100 or up, and after looking around at new sewing machines, it seemed prudent to just get a new one. So, after looking around, I settled on trying out the Singer 4411 despite it having a less than stellar review average. I like the fact that the 4411 is a manual machine (call me a control freak!) and that it's heavy duty. I don't use my sewing machine for a whole lot except hemming blue jeans and the occasional pillowcase repair, so I really just needed a solid dependable basic machine. When I first got my sewing machine in the mail and took it out of the box, I noticed that the needle didn't seem to be properly centered. This freaked me out quite a bit. Was my new machine already flawed?! Well, no. I discovered that you need to set the stitch width dial to zero for straight stitches. This moved the needle to it's normal center position. This is mentioned NOWHERE in the manual. Speaking of the manual...it's not too good. It's very "basic" (read: lacking), and frankly, if I didn't already know a fair bit about sewing machines, I'd be very confused. First off, you need Class 15 bobbins for this machine (which it seems to come with) but this isn't mentioned anywhere in the manual that I could see (it is on the side of the box though). Also, the needle clamp screw was tightened insanely (I had to use pliers to get it to loosen up), and the manual appears to tell you to move it the wrong direction to loosen it. Turn it TOWARDS you to loosen. Also, in case it isn't clear in the needle threading section, you need to loop the thread through that last little spot right next to the needle (I have an older machine that has a very similar threading procedure, so I recognized this pretty quickly, but others might not notice it since it's very subtle). Once you actually get the machine figured out, it seems to work quite well. I wound a bobbin perfectly, with no problems. I threaded the needle with no problems as well. All the wheels and knobs seem to work with no problems. I will mention that the light bulb is very dim, so you'll want to work under your own lamp. That's not really a big deal though. The very first thing I tested the machine on was some thick cotton, about 3 layers thick. Not a particularly difficult thing, but it had some seams in areas that made it quite a bit thicker (more like 6 layers thick in those areas). The machine ran right over them with no problems. I didn't notice the machine being particularly noisy or anything (but maybe I'm used to sewing machines making noise). Next, I put it to a more challenging task, sewing two layers of ½ inch thick batting onto comforter fabric. It did well enough, but you may need to loosen the tension a bit if you are having problems. I haven't really tested the button hole maker (don't need to use it) but I did try out some of the fancy stitches that came with it. Honestly, out of the few provided, only one looked decent. So, this truly isn't a machine for anyone who needs more than the basic straight and zigzag stitches. As for the accessories that came with it, they seem fine enough. The bobbins appear to be Class 15 (as needed but not specified). Also, you should be aware that even though it appears to come with different needles, all the needles that came with mine were medium size, so if you need another size, you're going to need to buy some separately. Not much to say about the rest, other than that the seem ripper seems a little dull... Overall, this is a good machine, and seems solid. As for it's label of "heavy duty" I'd say it might be a bit of a stretch. I haven't actually put it to the test, but judging from other reviewers, it isn't truly "heavy duty". If you just need to hem some jeans, it should work fine though. Really, I'd recommend this machine to anyone who just needs a cheaper basic level machine of decent quality (just ignore the "heavy duty" part and you'll be fine). If you're like me and just need a machine to hem a few pants and make a few pillowcases, this'll take care of your needs just fine! *Note: The first machine I bought was defective - the tension would not tighten no matter how much I turned the knob and the bobbin would wind all unevenly. I returned it to Amazon and had it replaced with a new unit (the one I have now) and this one seems to work just fine. This review is actually for the second machine I received, so if you get one that doesn't perform properly, be aware that it could be defective, and don't give up on it just yet!

Good machine so far!
I have only had the machine a week, but I know what quality is. I read as many reviews as possible before any purchase - anything over $30 I do that anyway. The multi-lingual "document" that arrives with the machine really isn't much help, for the beginner or the experienced. Other than repeat warnings to not leave it plugged in when not in use, it is mainly safety stuff. (Keep your fingers away from the needle! Simple and basic) The threading diagram and bobbin winding diagrams were a help, but the threading pathways are labeled on the machine. I have almost 50 years of experience with Singer and other sewing machines so I did not need much tutoring. A troubleshooting guide, like what came with my last machine would have been nice, but really its easier to YouTube how-to and the troubleshooting anyway. I was glad to read INTHE REVIEWS that the type of bobbin that this model 4423 takes- a clear plastic class 15 bobbin. NOT 15J, only class 15. Not metal. The machine came with one bobbin as the top thread and one inserted properly in the bobbin case, plus 2 spare. Be sure to check the stitch width and other settings before you start. Use zero for the width (mine was set at 4, don't use that) The center little indicator for the other 2 dials is best left alone (tension, etc) at the midpoint that is indicated by a TINY arrow. When you do sew, just like some other machines, hang onto your thread ends as you begin to sew, particularly if you are starting at a corner. If the threads get balled up under there, it's a mess. My mother's 1970's Singer machine used to do the same thing. It becomes a balled-up mess under there. It sews over thick seams like blue jeans have and does well. I did break a needle already- but I was replacing the zipper in my jeans and it was the last set of tack stitches at the bottom. I have only ONCE successfully sewn across in that area without breaking the needle, so no news there. Last piece of advice- practice on scraps so you can get a feel for using the foot pedal first! That thing is lightweight, and sensitive too. 0 to 60 in a leap! This is my 4th machine in 40 years, but I sew a lot and mend a lot. (Not made like they used to be made, but nothing is.) Nice touch to include a lightweight dust cover, and the right tools. I rate it overall 4.5 stars.

It's very nice, but I haven't used it. Is the voltage 220 or 110?
