I love the concept and their customer service is second to none. These guys do screen shares and you with your issues. Now, about the software...
I think that it's extremely useful and as I learn how it works, I've found tons of very profitable use cases. It's use cases and usefulness is not in question, but there is an issue. You can only run one agent at a time on a computer and cannot use your computer while it's working. In other words, you can program it it to do anything that you would do on the computer and it will do it, but it's not running in the background. It's using your computer instead of you. I plan on running scenarios from spare computers and eventually getting some RDPs in the cloud for it. If I can figure out how to run many agents at once, it will be the most useful software that I have and very profitable. I'm looking at there tier 3 plan and realize it would be exactly like buying 10 full-time employees, but just like employees, they need individual computers/servers. U-XER can definitely be a game changer!
