I emailed Marbles, described the problem, and asked them what they would do about it. They replied that a new compass is on the way at no charge. They are not requiring the return of the old one or any other nonsense. When the replacement arrives I'll probably use it as a backup to my Tru Nord. Perhaps the quality problems were due to a bad lot. Time will tell. I am happy to see that their customer service is still up to par and for this they should be commended.
