We had been looking for a suitable alarm system for some time, and struggled to find one that was easy to install, provided features such as 'cellular backup' and didn't require a camera (we'd rather avoid these over privacy concerns). Boundary is the perfect option for us! The delivery of the kit was prompt, it's all packaged very well, the instructions are clear, and for the most part it has been very easy to set up. The build quality of the components seems great as well, and there are reasonably cheap subscription options available. Over the course of the first week we've experienced some small issues that all seem to have been fixed by us circumventing our mesh wifi network and connecting the hub straight to the main router's own WiFi. Worth noting that Boundary have assured me that getting the hub to play better with mesh networks is due to be addressed in an upcoming update. Throughout any issues I have had, the customer service team has been excellent. Usually responding to any emails within an hour. Reasons for not giving 5 stars: - couple of teething issues with hub dropping out and a couple of resets required (solution found and hopefully some of these can be avoided with future updates). This is a new product of course so teething issues should be expected. - instructions and website state the hub can be wall mounted or desktop mounted using the stand that's sold separately. That stand actually isn't available yet but is coming soon. For me, wall mounting isn't an option, so would have been good to be aware of this in advance. Would be good if the website and documentation reflected this. - there are some differences between what's in the included instructions and what's stated on the online support materials (e.g. advising against any power extension cords for the hub, or advice against wifi mesh networks aren't present in both) To be honest, if I could I would have gone for four and a half stars! All around, great experience so far and product does everything I need it to.
