All I can say is that at 7.15 budget (where the ad has clearly not optimized yet), starting off 0.16 cpc is great. Potential is there, but you can't judge an ad based on that little amount. Just because you are not making money on your first X amount (lets say x=30), does not mean that that you won't have 100 sales with the next 30 (which makes it all worthwhile). Let it run.
