Then chances are we still have an adapter that works. Please see http://blog.kumja.de/zipper-brands/ for detailed information on the zipper issue.
When you order we automatically collect all information we need to determine which adapter(s) we send you. Usually, if we can not be sure about which adapter works, we send a "test set" that includes several adapters to try out. Pease don´t be afraid to order. You may cancel your order at any time in case you don´t want to get a test set, or for any other reason.
