Hi Wei,

WOW!!    Is my expression!!
I used my sewing machine today and found out it’s like a brand new machine!
So smooth ,quiet ,even stitches and can go fast as I want. It’s  very impressive.
Just wanted to say big THANK YOU!

Thank you for servicing my Bernina 550 sewing machine. She’s running like she was when she was brand new. I will recommend you to all my quilting friends! 🙏🏻Debbie
