The best #tech #support of any company I've ever interacted with comes from Prusa, the Czech #3D #printer maker. Consistently, they listen to what you have to say, and right away have a good answer. No how-are-you-doing-you-are-so-important-to-us bs that only aggravates everybody, but straight answers to each question, always backed up with links, sometimes with more background info than you had any reason to supposed might exist.
