I backed Boundary during the Kickstarter offering. It has been a long 2 years (prolonged by COVID admittedly) since then but the alarm has finally arrived. Packaging is good quality and well designed. The quality of product is very good overall. Removing the sensors from the base plates can be tricky until you get the hang of it, but instructional videos are included in the set up process. Set up of the hub, sensors and siren was easy and with the exception of mounting the hub, worked first time. There’s a fine line between completely tightening and under tightening the base plate of the hub to ensure the tamper switch is fully depressed. The fixings supplied are numerous and cater for most (all?) requirements. The app is good and with a couple of revisions, which I’m sure will be coming, it will be very good. There do appear to be some minor issues with notifications (turning SMS off in preferences but still receiving them, late push notifications for geofencing alarm/disarm), but I’m confident these will be resolved and put them down to teething issues. Support from boundary during the first week of going live has been exceptional. I’m slightly disappointed that the smart home integrations are not yet live, and no date has yet to my knowledge been fixed, but I’m willing to give some leeway with this being a new product. Boundary have given the Kickstarter backers 2 months free which is a nice way of saying thank you to its backers.
