I have used & worn out several Janome sewing machines over the years. I've never had any problems with any of them & I sew almost everyday, some days many hours @ a time. I always clean the lent after each project or every other day & take it in for a through cleaning, adjusting & etc. every 6 - 12 months. The one thing I love about the Janome is the needle & bobbin tension stays & doesn't change on it's own.
