I took my Janome in for a cleaning/tuneup this year after doing it by myself for about 5 years. I was extremely disappointed by the service. I thought they would go thru and check the whole machine out to make sure it was working properly. It was over $100. My DH had to redo the bobbin tension whe we got it back, the bobbin winder still does not shut off, the alarm doesn't sound when almost out of thread and I had to recalibrate the embroidery stitch. I will go back to my own maintenance or find a recommended shop next time!
