:-) Yeah! love it, don't have to play with the sewing machine if the bobbin I am using runs out. It did take me about an hour to get it working right the first time. Per previous posts, you can adjust the tension and also manually stop (very easy) if it tends to overfill your bobbin. The instructions are not useful; had to figure how to adjust etc. myself.
I have a Bern ina Activa 220.
