Review on Incredible Threadable Embroidery Box by Madeira - 40 Spools, 1100YD/1000M (20928042) by Kristen Simpson

I have a Brother 770 embroidery machine and the Madeira thread keeps breaking. I've threaded several times, checked the spool, adjusted the tension, consulted my brother dealer and followed their checklist to try and get this thread working. All other brands of thread I've tried have worked great. My advice: buy a spool of Madeira thread before buying a box. The thread itself is beautiful, the box is well designed, and wawak's customer service has been great.
