Hello. I bought 2 Koralia 4's from Amazon.com in June, and one of them has stopped working. I figure that there is a manufacturer's warranty on these, but when I go to Hydor's page, there is no contact information whatsoever. Has anyone had any experience with this, or know how to contact them? I'm going to send an email to amazon.com about all of this, but I'm not expecting much help there. All replies are appreciated. Thanks!
