Very happy so far with the Boundary alarm system. Had the system installed for a few days now, with just the siren to put up. A doddle to setup. App is great, intuitive and actually reliable. unlike a much bigger competitor (beginning with P) who have got no idea how to make an app that can talk reliably to anything and then refuse you talk to you for not being a trade installer. No such nonsense with Boundary I have to say! A couple of niggles here and there but as others have mentioned this is a brand new to market system and its backed up with great customer service. Components are great quality and sensors easy to pair to hub and install. I'm sure this will get even better as more smart features are added but it's fantastic as it is now to be honest and light years ahead of the other system I had.
