I've had one(mission to mars) and I was really excited about it, but sold it within few months, the build quality was just so bad. Mine had two specs of visible dust on the dial, the hands were not alligned correctly, and worst of all the quartz movement that they use is actually crap, you can hear it tick from across the room it's such a bad movement. I actually went back to the store to compare with several other moonswatches that they had there and they all had some kind of factory defect like this. But you know, in any other watch I'd probably pay a local watchmaker a tiny bit of money to open it up, clean the dust, align the hands and be done with it - but in this one, you can't - it's all sealed up, the movement is literally disposable.

I also have an actual moonwatch and for me personally I love the idea of a "fun" moonswatch to go with it - but at the quality currently presented it's just not worth it, I wouldn't buy one again.
