I would recommend this to a friendDecent with a good value
||Posted . Owned for 2 weeks when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.This ring device is decent but its sensitivity & function could use an improvement because in real life, a burglar is not going to walk a certain way to ensure that the device gets triggered if you understand what I mean. So, overall, this motion detector device will do the job as it. Ring will be releasing a newer model in March 2026 which supposed to be somewhat of an upgrade in its sensitivity & function which is a little pricier.

Owned for 1 year when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.Knocking a star off for the setup process which only goes through 50 % of the time. Works well once setup and sometimes the battery life is sometimes 75% or lower sitting in storage.

It sounds like you are experiencing issues with the device in regards to setup process. The Ring Alarm Contact Sensor (2nd Gen.) allows you to expand your Ring Alarm system to secure each door and window in your home and get alerts as soon as they open. The Ring Alarm and all Ring Alarm accessories require a subscription for in-app features and digital notifications, including digital arming and disarming and integration with other Ring, Echo, Alexa, and third-party products. If a Ring Alarm Contact Sensor fails during setup, you may have to adjust the position of the magnet and sensor. Move the sensor closer to the magnet or in a more optimal alignment.

Paired with Ring Alarm
|Posted . Owned for 2 months when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.Easy to put up & add on to work with your Ring alarm. This allowed me to have the amount of sensors I wanted throughout my home. They were easy to put but the adhesive that comes with doesn’t work well. I used the scotch double sided tape. Surprisingly the tape worked better than the adhesive did
