I have one of them too. Bought one Ekich bobbins and it has a lot of very nice features, but it drives me crazy and the spring in it doesn't re-set auto and you have to use your thumb and fingers to push the spool away from the little teeth that hold it from turning so it will turn and release the tension. I mean it's very well made and all, but like I said it makes me crazy and peeved.

Hope I made that clear, but that part I don't like and it's what I do like about the Nor-Vise one.
