MediaBoost "Adwords Booster"

We're running the free trial of the Adwords Booster tool, from MediaBoost.com. In principle it seems like a great idea - it does a statistical analysis of your account history, then adjusts bids daily right down to the keyword level and watches results, adjusting along the way.

Anyone have any experience with this thing? We saw some impressive results earlier this month. Everything slumped last week (we're B2B), which I'm sure is seasonal, so I just have to wait for business to resume next month. Meanwhile, I thought I'd see what I can learn from the masters here.

I gained some considerable concern about this approach, after reading posts from Rose and others about the weird spiky behavior that happens after some changes, e.g. deleting broad match. But if bid fiddling doesn't trigger those responses, then maybe this approach could work.

I think the MediaBoost folks are solid, and the service is solid. I tested over the course of 2+ weeks using a few thousand dollars with one of the client accounts I manage, and their boosting engine performed well. It did about as well as I was doing manually, which is very good (you save the labor of doing bid optimization yourself).
