First of all: it is very easy to setup, even for someone who is not technically fit. The system is pre-configured out of the box and the only thing you have to do is to plugin power, pull some battery protectors, stick the sensors to the appropriate places and add the main device to your Ring account.
The package comes with one month complementary professional monitoring and you can subscribe to the service for C$15/month afterwards. If you decide not to subscribe, you will lose the professional monitoring, but everything will keep working with the exception that there will be no cellular backup if your internet fails, and nobody will be dispatching police in case of an alarm. The price for the subscription and the initial costs for the set is one of the lowest on the market.
Why 3 stars and not 5 you may wonder? Ring is advertising services like "Neighbors by Ring" and options to connect third-party devices like door-locks or garage door openers via the "Works with Ring" program, but they don't tell you that many of these are not available in Canada (-1 star).
Regarding the door lock, we have Yale Z-Wave locks which connect easily with Ring, however, we found a huge no-go: once the lock is connected with Ring it will share the same codes with your Ring (which sounds good, eh?), but the code is limited to 4 digits only. This is unacceptable and probably the biggest security issue we have found. (-1 star).
Summary: we have decided to keep the Ring Alarm but removed the Yale locks from the system to be able to have longer and therefore safer door codes. We are also hoping that features available in other countries like the US will eventually make their way to Canada as well.
