    I needed this to get statuses of my patio doors and use them with Hubitat....exactly what I needed and perfect for my application. They are little on the big side compared to others, but dont mind it. Easy to install and sync.

    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.

    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!

    The ring contact sensors are by far one of the best additions to my ring security systems. The base station allows up to 100 wireless sensors and divices, so I can keep adding them if I need too.

    Good and quick, easy installation myself (it would've been a hassle to get total tech to do it when I set up everything else myself). Reliable. These worked fine. I've had some problems with the ones from Amazon where 5%-8% of them don't work. No problems with the ones from Bestbuy.
