    Works as advertised. Installation was simple and easy to set up in the app. These are definitely better than the first generation because they are slimmer. The first generation looked like they stuck out more vertically.

    There are many home security products out there. And while this is no different than others what I find best about this product is easy to setup and use. And compatible with other gadgets in my house. So far working like a charm.

    These sensors are the perfect fit for any window or door. They tuck up out of the way and are not an eyesore. Small and very easy to set up with your ring alarm. It takes you through step by step.

    Easy to install and more mounting options due to smaller/slimmer size. This second gen takes batteries that are easier to source and purchase locally without having to order them online...

    Great Sensors for Ring. Available at Best Buy

    I needed these to add on to my Ring system. Am-xx-n didn't have them in stock. I ordered them from Best Buy and they arrived in 4 days. The sensors were easy to install after watching the Ring app's videos and reading helpful reviews on the online store site. The Ring app recognized the sensors and the sensors have been working. Only issue is not being able to reposition the sensor once to place them. The sticky tape is permanent. Be sure to try to place them right to allow room for sliding off the base when you need to replace the batteries for the sensor.

    Contact sensors were easy to set up and configure, and at the time I purchased these, buying a multi-pack made them cost less per device than buying them individually (equivalent to getting one sensor for free)!

    I bought these ring door/window contact sensors because I needed two more sensors after installing all eight sensors that came with my Ring home security system. So far, the sensors are working exactly as advertised. Excellent!
