Review on 🧵 Ever Sewn Sewing Machine Bobbins 10 Pack: Long-lasting bobbins for efficient stitching by Dawn Fischer

I am so disappointed. I just bought a new Eversew Sparrow 30 and was happy to order these reels. When I started sewing after bobbin winding, I noticed that my stitches were either too loose or too tight. I've tried everything to adjust the tension, put in a new needle, make sure the bobbin carriage is working properly, etc. but to no avail. I took my car back to the store I bought it from and they tried using it and found they had the same problem. They gave me a loan and I came home and started sewing, put the bobbin in the machine. Miraculously I had the same problem with the seams not coming out properly. They gave me a spool that they wound up. I put it in the machine and started sewing and to my surprise everything was fine. Obviously these coils are not universal. I've put a lot of time and effort into threads. Send them back for a refund.
