Review on Simthread 25pcs 90WT Prewound Bobbin Thread Set: Size A Class 15 (SA156) with Storage Case - White, 60S/2 - Perfect for Brother Embroidery and Sewing Machines! by Kristen Simpson

I'm running out of fast forward reels and I've seen Sim Thread get great reviews. Also some people in several embroidery groups swear by it. So I bought prewound bobbins. Oh god, I've never had so many bobbin thread problems in my life. I worked making key fobs - key fobs with light stitching and they broke and tangled. Now I sometimes have problems after putting the coil in for the first time, so don't hesitate. But no. I spent all morning with a broken bobbin thread. Again and again and again. So I used one of my remaining ThreadsRU prewound bobbins and sewed them together beautifully. What was even more encouraging? The package came with a thread, nothing more. I don't even have the luxury of trying to return it for a refund. At least it came in a good case - I can use it. But I will never buy SimThread again. No wonder they try to give away their product. It's not worth spending money on.
