Review on 🧵 Electric Automatic Bobbin Winder with Spool Thread Stand for Sewing, Brother, Babylock, Singer, Janome - Convenient Accessory for Automatic Thread Sewing Machine and Bobbin Winding by Michelle Langley

Came with illegible assembly instructions like the others. I watched videos on You Tube to find out how to do it. Why couldn't it be assembled? I now see there is a short video and instructions in the Revain product listing, scroll down to see them. Once assembled, it took some effort to get this thing up and running, but once set up, it winds coils incredibly fast. Mine doesn't stop automatically, so I have to be there to turn it off in time. While the coils look fine, I wound grade 15 metal coils for my 1952 Singer 15-91. I have not tried bobbins from other brands of machines or plastic bobbins. It's nicely wound from thread cones, the spools don't work and fly off the spindle when the machine spins. This is disappointing because I use spools of thread instead of cones for sewing. Once I get used to this curler I think it will come in handy. It took me several hours to set it up.
