I have only had the machine a short time and have used it for only the basics (seams/hems). On the whole, it works very nicely and the manual is very helpful. The automatic needle threader has not worked from the first use and one day the motor felt like it was running on run-down batteries. Otherwise, so far the machine has operated smoothly. I wish it had come with a storage case and I haven't figured out how to overcome sewing over thick seams (e.g., when hemming blue jeans).
