The user experience is great as it makes all of our operations much more efficient in terms of time taken to find information or fix issues with production servers at scale across several continents (we are US customers). So far there has been no downside but I have not used any other product yet from them either so nothing else that would come up if you were looking into using one particular feature versus another. We use redsmini primarily because we can see what keys/queries make queries take longer than others which allows us troubleshoot those things quickly rather then having someone spend hours trying figure out why they don't work well under load etc..
