There's an old saying: it's not the fall, it's how you recover. I'm a long-term customer and fan of Theory11, but for the first time ever I had a significant problem with part of an order. It turns out Theory11's excellence in design and (typically) quality extends to their customer service. I went from being upset and disappointed about part of a product to being so impressed with how they handled it that I think I'm an even bigger fan of theirs than I was before, despite having had a problem! Hats off to Mandy and the customer service team at Theory11!
