    Ring provides great products at a reasonable price. Their products are easy to install and provide an easy way to create a 'smart' home within your existing home. I'm most pleased with their subscription service. Their annual subscription service is equivalent to one month of service from Vivint!

    We needed to upgrade our security system at home and the Ring system was an easy, efficient option for our needs. It is economical and easy to install. Their customer service team has also walked us through a few questions and have been incredibly helpful!! We would definitely purchase the Ring system again and this 6 pack of sensors to easily monitor several doors or windows.
