Ugh!! Hate it!! I bought it to use one half for sewing and one half for embroidery bobbins. It's flimsy and comes apart too easily. If the bobbins are not full, they began to unravel themselves anyway and the thread ends are everywhere. Still looking for something better. The only other gadget I hate as much is the Fons and Porter seam ripper. That thing rolls off my work area constantly!
