I have only had this item a few days but I couldn't wait to try it out. The stitches are well formed and even. I have had no trouble with tension issues, snarled bobbin thread, broken needles or thread. I have not attempted hemming jeans yet, but it EASILY sews through 4 thicknesses of denim.
The included instruction manual is easy to follow. I like the pull out handwheel feature which disengages the clutch. It is much easier than trying to turn part of the handwheel, when aging fingers and hands don't have as much strength as they used to.
Although this does not have as many features as a computerized machine, I am happy with my purchase and plan to enjoy it for years!
