20 Pack Class 15 Clear Bobbins Made to Fit Singer 006066008

I recommend this product

I had previously been buying the Singer 4 packs from Walmart, for my Singer Start 1304, but they haven't had them lately. Someone in their review said a Singer rep said their bobbin company put out a huge batch of BAD Bobbins they were unable to recall since there were no lot numbers, hhmmm interesting. So far I am happy with this 20 pack of bobbins that fit my Singer Start 1304, and they seem to load more evenly then the others I bought at Walmart. I haven't checked all 20 of the bobbins, so can't say if there are any defective ones. I will update if I have any problems with them.

TL;DR in title. These bobbins work well with my Singer Heavy Duty 4432 sewing machine. They're a smidge taller than the bobbins that came with my machine (11.5mm vs approx. 11.3mm), but otherwise, these bobbins work exactly the same as the originals, in my experience. Your mileage may vary. Regarding the durability of these bobbins: I was unable to break or warp one on purpose with my bare hands, but I did break one accidentally by stepping on it. For comparison's sake, an original Singer class 15 transparent bobbin deformed when stepped on, but did not break. With my scant data, I conclude that these aftermarket bobbins, while more fragile than Singer's original class 15s, will most likely stand up to normal usage. Treat them kindly (i.e. don't be an idiot like me, not even for science) and you'll be fine. At present, I'm happy with my purchase. If I run into any problems while sewing with these, I'll update my review.

I got a new Singer heavy Duty Sewing machine in which you can see the bobbin and I love the fact with these you can see how much thread is left in the bobbin. I will be ordering more of these. I a very happy with them.

I would buy it again
