I purchased my Bernina in 2005 and had it serviced after the first year as instructed. Since 2006 I had serviced her myself being careful about oiling and cleaning out any lint and changing the needle with every project or before, if needed. I decided to take her in so I made an appointment and took her in today. I picked her up about 4 pm and could not wait to get her home so I could check her out. She is so quite and the top stitches and bobbin stitches are perfect. You cannot tell the top from the bobbin stitches. I wish I had had her services earlier. If you have not had your little darling services in awhile, you may want to consider having it done. Happy Quilting!
