I like that it has a lot more functionality than other products in this space, with good support from the team behind its development as well! The UI could be better - there are some things which don't seem to have been thought through very carefully (or at all) and others where they just haven't bothered putting any work into them yet because no one uses those features so why bother? It's also slow compared with competitor software; however we're working towards improving our speed once again by implementing new technology soon.
We've used various systems over time but none compare to the ease-of use and flexibility available within tracwire rmp.
