i like that you can use this in different ways, if someone has an issue with their property then they are more likely to respond/ go through your system first rather than going direct via there phone line or email etc which saves alot of time! it also allows me as admin access so I'm not required to be physically present when issues arise.
its quite expensive but worth paying up front because after 12 months we have 100% uptime (no faults) meaning no downtime whatsoever - perfect :) would highly recommend using responseimpact where possible instead of relying solely upon landlines and emails only being useful at certain times during day / night hours!
