Brought this after seeing a youtube video from Artisan Electricians as I my current wired system was out dated and unsupported and after completing research Boundary was one of few company who provided up front pricing. Packaged arrived within two days of placing order. I will say it was well packaged and presented in an order to of which package to start with first as per the manufacturer's set up process i.e. Hub>Sensors>Siren, which I found extremely helpful. Very straightforward to set up the alarm system installation via the boundary App once I created an account and set up the hub. Like any self install system I did come across a couple of gremlins, which the customer care service were second to none in response within business hours. No hesitation on replying back to you and the team provided the relevant information based on the email that was sent which was well written. The customer support are very knowledgeable and very keen to get you up and running, even go so far to add additional messages to make sure everything is running smoothly in support of the help topics. It's also nice to know that this company are uk based and have taken feedback positively to further the systems usability. One area that Boundary should be more clear on is that a monthly plan is really required if you are intending to use more that the 2 users and 2 sensors, which in my case I had no choice but the use the subscription service, which I didn't mind paying the fee of £8 a month or £96 for the year. I Would not hesitate to recommend this smart alarm system as I feel I have more control over how I use the system as I'm informed of any outage or suspect activity via mobile device. Plus the prices are advertised not like some other national alarm companies who want to provide you with a quote, which for me is a big no no. Paul One happy customer
