I put in the minimum of $50 and had it going from Thursday morning Eastern time to Saturday. I had a limit of $10 the first day and $25 on Friday, leaving $15 on Saturday. In all, I had about 80 downloads. Since Saturday, I've only had about 20. I found admob good for traffic, but there were no ratings and feedback at all. Total impressions were about 290k with about 1250 clicks.
