Purchased the boundary system after initially learning of it's existence back in the kickstarter days, didn't buy it then but since it's release to the general public and word from boundary staff that Apple HomeKit will be supported later this year in 2021 I decided to buy it & I certainly do hope this will be the case with Apple HomeKit support. Anyway, after the purchase I received the box with all this alarm kit in that I'd ordered. The whole experience of unpacking seems nicely thought out, all the parts are nicely packaged and look very well made. Instructions seem clear enough. Just in the process of doing some diy so I haven't as yet installed the system, but once I've finished decoration etc it'll be installed. So at the moment I can't comment on the working system but I'm very happy so far. :-) It's a nice piece of kit.
