    These Ring door sensors are a great addition to the Ring system. They are easy to mount both with screws and double sided tape to any door or entry way.

    These are a breeze to install and set up, but I had two that were being difficult and I had to reset them a few times before they would sync, so quality could be a little better. Still, I would recommend this for adding windows and doors to your Ring system.

    Quite big for window/door sensors but they do the job to make sure all openings are protected. Wish they’ve made it smaller one day.
