I have had my Boundary Alarm system for a few months now. Set up was very easy, and getting the ladder out was the hardest part to mount the motion sensors. It has not been without a few teething problems and several sensors have 'fallen to sleep' or dropped off the system but the Support Team has been very helpful and for my garage provided a Z Wave extender free of charge. Since then the Garage sensor has not dropped connection once but the one on my Bi-Folds I think this is more to do with the fact these doors are Aluminum and this does mean you have to think more about how you mount the sensor. Another positive is new features are coming online regularly and the stability improves all the time. One thing I would like to improve is the cost. I paid for the alarm but having to pay an extra £9.99 per month to add a user is a bit much. I get the monitored system requires a subscription but the standard alarm cost should; cover things such as users etc. Overall I am very happy with the alarm.
