I've not loved the 15 clones I've had for FMQing, yet my true 15 is wonderful at it. So, I've found new homes for most of my 15 clones. I would suggest you bring a quilt sandwich to try it out and see... It should be a vertical bobbin. It's a clone of the 15, so a clone of the vertical bobbin assembly. Maybe the seller got her vertical and horizontal mixed up like others do. hehehehe:> For only a few $ more, I'd stick with the Singer 15.
