Mikkel Qvist & Andreas Andersen are very professional providing constructive solution to arm my house and provided convincing answers to my questions related to usage of the alarm system, the maintenance and the relevant services.

Unprompted review
Daniel
Daniel - installation technician, is truly a man for the job. To me he had perfect balance between being professional and being human. Regarding the system itself- works as agreed - but its also one of those systems that I want silently do its job, never really use its full potential :)
Yet after failed disarming procedure we figured fast that G4S reaction time is lightning fast and they do exactly what Daniel explained they will - recommendations from here

End to end great experience
End to end great experience, starting from customer service representative Daniel to the system installation professional Thomas.
Friday I got a quote and Tuesday the system was installed.
Lots of flexibility in adding gadgets and services.
