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.

Easy to set up!
||Posted . Owned for 1 month when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.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)!

Great Sensors for Ring. Available at Best Buy
||Posted . Owned for 1 month when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.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.
