We have been using it for a couple of years, and I concur with the others. It's the best site search we've tried, but it's not a big money-maker. The CTR is very high, which balances out the low CPC to make a decent CPM, but this doesn't translate to much earnings since we get no more than a few hundred searches a day. We've actually considered turning the ads off for simplicity's sake, but it's hard to resist those few extra bucks.
