Pro's- lots of cute and traditional single pass quilt designs and looks really good when finished
Con's- depending on quilt size a lot of work; hooping and unhooping 3 layers and aligning each time. The lining up each design can be tricky and time consuming each square will have to be centered and it takes up a lot of space, again depending on quilt size. You need a table to support the weight of the quilt while its running or the weight will pull and distort design or worse break machine
That all being said I used mine 3 times to do the quilting for me and I will probably do it again tho nothing larger than a baby quilt or crib size it is just too much for me on anything bigger..I have done a twin, full and baby quilt this way the full size was the worst I thought I would never finish.
