Be patient folks, just remember whilst you may have 600 USD riding on this project people like Matthew and the other guys working at PIMAX have staked their jobs and reputations on this product.The potential risks for us as backers is pretty minimal comparatively.
At least PIMAX has had the courtesy to A: apologise and B: set a delivery date. After having backed Star Citizen PIMAX customer service is like a blessing, perhaps my patience is more tempered than most!
