I have both the 20 and 30. Like both of them for travel and retreats. I had an issue with the first 30 and contacted their customer service department. No questions asked about it after I told representative what happened. They immediately sent out Fed Ex to pick it up and within a few days sent a new machine. I can’t say enough good things about their customer service. Also I was having a bit of trouble getting the settings right on the 30. Wasn’t sure if it was me or the machine. Took it to a Bernina dealer and he did some minor adjustments and it works great now. Best part, No Charge.
