I like that it allows me to see my ad spend in real time so that we can make decisions faster and more effectively. It's also easy to use and requires little training. The only thing I don't like is that sometimes you have to wait a few seconds for the data to refresh. That's not too big of an issue since most people are probably not looking at this screen every few seconds anyways. If you're looking to improve your PPC, then give this tool a try. You will be able to see exactly how much your spend is costing you and where you need to focus your efforts (i.e keywords). This has been extremely beneficial for our team.
