I see some negative vibes here on the last page from costumers. Honestly, if you spent $250 worth of ads for less than $100, why are you arguing? Go and fuck off to AdWords yourself and spend your money there.
Now, my experience:
I had already 5+ accounts from this seller, it's all working fine. You have to know what you ask for, give him the requirements and he will fill them. He created MY ad every time I ordered. I told him what and how I'd like to advertise and he created the ad, which already got impressions and clicks. I just kept it running until it drains out (gets banned after a few hundred spent, sometimes even thousand). Once you start making changes to the campaigns, you will become suspicious and they will review your account (get you banned) because only an idiot would raise daily budget from pre-set $25 to $250 all of a sudden, or change ads to reflect a completely different website in the same campaign...
We had some problems in the beginning, but seller resolved them in a matter of hours. I am patient enough to let him breathe and do not expect him to respond in a minute, so we went along pretty good.
My score: 5/5
Thank you.
