It arrived last Wednesday, but only got time to unpack and try it today, and it's going back
It's just so fiddly to thread, didn't like some of the thread I used, and I think the top cover stitch bit looks a bit "Heath Robinson" and it takes such a pull to get the fabric off, it'll never work with stretch fabrics.
I don't think it's me being not very good with it, I've used overlockers and normal coverstitchers with no problem, but this I'd just not bother getting out to use. Very disappointing.
