I know this product for quite some time, but now it has a new interface, which is more user friendly and also all the old functions packed for performance and usability. I find it very easy to be used and intuitive. For some time they have some 30 days free trial which i strongly recommend if you are now to monitoring or do you want to check all the new stuff SmartBear is providing with this tool.
I would have wish for more recording apps. Currently to load your test you would need to download DejaClick and record your steps and after you would need to play it back with smart-bear, but before doing that you would need to upload this to the smart-bear site, which it is kinda complicated. Also it would have been great if smart-bear playing capabilities would not stuck when a new loin key is provided when you do the jumps between api's. In few words I am still not able to log in in one app and jump in another one with the same ssh key and smart-bear to be able to play this recording, it will get stuck because the ssh key will not refresh in smart-bear chrome or firefox.
Take your time to read and search google for how you should use and whit what software it is integrated.
I'm doing all kind of monitoring with this, but mostly the availability of the servers, up time of webpages and responses from webpages, this can run for a long time and you can have some report over a long period of time.
