A well-designed product is not just one that had a clever idea in the concept. To be a well-designed product, it must also be reliable, usable, and above all have great build quality. As someone who bought one of these and threw it away in disgust after being unable to open it once I supposedly set my own combination, I'd never call it a well-designed combination lock. As uptown says, the reviews on Amazon alone bear witness to the fact that this is a shoddily built lock which often fails one of the only tests that really matter for a lock, namely, can you open it? I'd rename this article "A really clever idea for a combination lock (that failed in execution)."
