I decided to upgrade my machine after getting to demo the Janome 500E. After doing some research the 500E has had some issues with tension, right out of the box. I found this to be true with the one I got. After working to figure this out I merely changed the bobbin from what the dealer had given me, Janome prewound bobbins. Well that was the problem. I changed back to the cheaper prewounds that I had used before and the stitch is beautiful, with no adjustments at all. This is good info for those that are having these tension problems.
