First off, I think this one is from China. Casting is a bit rough. Manual probably copied from somewhere else and done by someone with poor English, lots of typos. Diagrams not too clear and one seems to be missing. Good thing I know how my old one works. The threading is OK but the needle eye is only just visible on the highest point. I had to use tweezers and get a strong light on it. I think someone with poor eyesight would struggle. Probably explains why factories use that horrible 'invisible' thread for everything. I still want to match my work though.
The tension holds the mono-filament well and it does a neat stitch although not quite as invisible as my hand stitching. About a million times faster though. It gallops off at 1200 st/min which makes it hard to control. They do supply a clamp to stop it coming off the table! I've only just unpacked it though and need to play with the settings yet. Haven't worked out what size needle is in it. It had better not break because I can't shift the needle clamp screw, might have to call in reinforcements when it does. Ditto on the wing nut that holds the work surface.
This one has no light, being industrial type. Locks off the thread well, better than the old one.
Overall, I get the impression it is a bit more 'focused' than my straight needle Babylock, which is old and second hand. The build on that is very good as you'd expect.
When I get a decent set of samples will come back and add them. Just talk among yourselves, this could take quite a while. (i.e. not today!)
