    My wife loves this sewing machine!

    My wife is wearing this machine out! She absolutely loves it! I, personally, know little to nothing about sewing. So, my review will not be the most thorough in that regard. She loves the features and the preset stitch patterns. She brags on the machine every time she uses it, and let me tell you.... SHE USES IT A LOT!

    JUST BUY IT, SO GOOD

    I've never had a modern machine. I've always had Singers over the years that were decades old from church auctions and I've spent the last 15 years sewing with my grandma's 1960s model. I always knew there was something better out there and I've been waiting my whole life for this splurge. If you've sewn before, don't be intimidated by this machine, it's intuitive.I was initially hesitant as there's so much online hate for Singer in recent years since they were acquired by a larger company...but I wanted something familiar so I went ahead and got the upgraded model with all the fancy stitches

    Happy Customer Here!

    I am really enjoying this sewing machine! It makes beautiful stitches, runs fast if yiu like. I love that I can have an extra spool on top to fill bobbins without unthreading the machine. It remembers up/down needle from last selection. Very happy 😊 with it!

    Don’t buy this crappy machine. Safety issues, not working properly, awful service from Manufacturer.

    This is the worst machine that I’ve ever used. In just one month of use the machine started giving problems. When trying to solve the issue I contacted the manufacturer and they didn’t provide any solution. I bought it by the end on May, received it on June, and started using it early July. It began acting up within three weeks of use. The machine continues sewing by itself without pressing the foot pedal. It’s like a ghost is working on it! And suddenly it’s sewing full power. It’s a safety issue and obviously has damaged several projects. The most frustrating part is the lack of support from

    A good heavy duty machine!!!

    Very satisfied with my purchase. I needed a heavier duty machine to make rope bowls and this works very well. Easy to use, quality is good, not overly noisy, and good value.
