    These are a required purchase when you’re trying to secure your home. The sensors are incredibly easy to install and work great to let us know when we leave a window open.

    I needed extra Ring contact sensors for my house. Bestbuy was the only place I could find the convenient 6 pack set. These work wonderfully and are super easy to setup.

    Excellent product that you can truly install yourself! I put the whole system in and it only took me about 2 1/2 hours (this was just one piece of the system).

    I got this 2nd gen 6 pack in order to complete my home security set. Super easy set up with the ring app. These are super tiny in comparison with the 1st gen. 100% recommended.

    Easy to install - easier than 1st Generation but they are larger so harder to fit on the side of the window. It also tells you to install so you can change the batteries but there isn't room. Hoping that I will be able to take them down and stick them back. Works great
