Perfect product.
The bobbins could be improved by putting holes in them to pull the thread though when trying to wound them. I find the process of wrapping thread around them multiple times to wound the bobbins is frustrating. It takes several tries before it works on the Qnique. When you are short and senior, doing all this above the shoulders (because it is on my frame) results in pain.
I purchased a package of 10 during one of the sale events and was very disappointed with the quality. Seven of the ten could be wound, but three would just sit on the spindle and not wind since the hole diameter was slightly too large. The three should never have passed quality control and very unexpected coming from the Grace Company.
