    I have these at each door in my house. There is an alert every time a door is open and my ring dashboard shows when a sensor is cleared or open. I had to add a chunk of something to my door in order for the sensors to connect with each other when the doors are closed, but aside from that they were very easy to install and haven't had any technical issues.

  • 2nd Gen Ring Window Door sensor

    This reviewer received promo considerations or sweepstakes entry for writing a review.

    The sensors are pretty good and can fit most places. They are also very much more sensitive than the motion detectors. The range from the base station needs to be considered as the signal can be weak at a not so far off distance, especially in basements. I wish they were even slimmer and lower profile and I wish they informed us if they were connected to range extender or base station. You have to keep the app on and keep looking at it to know if the distance between the 2 pieces is close enough to work. A little pricey for what it is.
