Decent 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.

Good contacts, software buggy
||Posted . 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.

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
