I had a number of setup issues with my alarm having purchased it just after release and this required me to contact support. They were very attentive and worked through the issues with me, giving my options to resolve the issue including sending out a range extender free of charge. I'm all up and running now and feel like my custom mattered to the company. I would give 5 stars if it were not for two points: 1) the issues I encountered were definitely teething problems with a new product, but suggested the initial launch should have been run as a beta; 2) the support resolution was all done via email which resulted in tens of emails - there should be a chat system for this.
