They have made good upgrades to the system to help fit our needs and hopefully benefit their other users.
Customer and Tech support is excellent and Cust Relation Manager are very eager to help you. We are using xmatters for our critical Control M Alert function and so far our End Users are Happy.
I have had nothing but great communication, help, and training from the xMatters team. This software is excellent and easy to use.
As a user, I find the interface to be extremely confusing, even frustration. Even after I've figured out how to do something, next time I need to do it, I have to re-figure out how.
Integrations have been somewhat challenging and professional services disappointing in the time required to get things done.
The one area which didn't work well was the phone alerts where the combination of American and English 'voices' gave a disjointed feel to the message.
