my mother has had a necchi for many years- she loves her machine...i don't know anything about it other than she's been using it since the early 80's when she bought it at some sale at a holiday inn where they were demonstrating them- they were ones used in schools- so built to last through lots of abuse, wear and tear- and her's has lasted- i do not know of problems she may have had over the years, but it works now.
