**SINGER 4423 Heavy Duty High-Speed Sewing Machine with 97 Stitch Applications | Strong Motor, Metal Frame, 1-Step Buttonhole, LED Light & Accessory Kit – Perfect for Quilting, Upholstery, and DIY Projects**

I just purchased this Singer 4423 Heavy Duty sewing machine and have only had it for a couple of days. I will use it for doing simple repairs on clothing. I'm a 67 year old man and have never used a sewing machine before, so I can only attest to the machine being easy to setup and operate. I did have some problems with the bobbin thread balling up in its compartment, but that was due to bad thread. Once I purchased good quality thread that problem was solved. The instructions that shipped with the machine were pretty sparse, but I downloaded the manual from Singer's website, plus several videos on YouTube that detailed the proper maintenance and operation of this particular model sewing machine. Only time will tell if this machine holds up over the next few years. My best advice is to experiment, be patient, read the manual thoroughly and take advantage of the many resources available on the internet for this machine!Update --- Since receiving this sewing machine I have sewn nylon webbing, leather and other thick fabrics!! I just repaired a cellphone case and this machine went through two thin layers of leather and a cardboard insert! I just love this sewing machine and hope it holds up for a few years!!UPDATE: 08/09/2021Well, I've had this Singer 4423 sewing machine for a few months now and still love it! As I previously mentioned, I'm a novice when it comes to sewing!! Since my initial review, I have sewn several pot holders, aprons and have now completed 3 Hawaiian shirts, 1 work shirt and am currently working on 2 western shirts! I must admit I have experienced many of the problems other users have complained about, but these were solved by simply taking the time to read the manual and doing a little research on the internet. This is a simple and reliable machine and if you take the time to do your homework it will serve you well though many projects!!Update 02/13/2023: I've had this little Singer 4423 HD for almost 2 years now and can't say enough good things about it. I have sewn everything from quilting cotton, to denim and even some light leather with this machine and it has never let me down. I believe this machine is the best unit at its price point!Update 10/06/2024: Well, I've had this machine now for almost 4 years. I can't say enough good things about this Singer 4323HD sewing machine. I've run both light and heavy fabrics and materials, the latest being heavy Cordura, through this machine and it has given me perfect stitches every time! I must admit however, that I'm pretty anal about cleaning and properly maintaining my equipment. This little machine just keeps performing beyond my expectations for its price point!!
