This is a great product! I read through some support articles before getting started. I thought I knew everything and ended up wasting time because I didn't realize you could clone reports. There are only 2 real weaknesses I see -- you can't display multiple Google Analytics accounts in one report (if you do, it aggregates all the data) and there are a few things they don't integrate with yet (like Vimeo and a few others). There are workaround,s though, since you can always upload your own image or spreadsheet. And I still think it's very easy to use and better than similar products I've seen!
UPDATE: Great news on two fronts! First, a representative from DashThis saw this review and contacted me to help clarify my concerns. Excellent, proactive customer support! Second, he let me know that you can now have multiple Google Analytics accounts in one report. He explained to me how to do it and helped me update one of my client's existing reports. This will save me a lot of time in the future, plus it provides more streamlined reporting for my client (as opposed to the workaround I'd been using).
We were spending a lot of time providing monthly reports for our clients that were simple, unflashy Word documents. DashThis reports save time while producing a better-looking report that allows clients to view their stats more easily at a glance.
