It's lovely! I don't have anything to compare it to, but it seems smooth and solid, the bits I've tried have stitched beautifully and it has that lovely new machine smell (Mr Acorn say it's the smell of plastic with just a hint of oil...
).
I now have my embrodiery machine, overlocker and coverstitcher on the dining table, and my old faithful Pfaff and Featherweight with buttonholer in my study/sewing room. I'm set up for anything!
My only criticism would be that it doesn't have any sort of cover - not even a floppy plastic one, although it came in a pretty tough plastic bag which will work well as a dust cover.
