5.0 out of 5 stars Like new! Great discounted price!
Reviewed in the United States on March 28, 2024
I purchased these as additional sensors for my new place. They arrived in a Ring box sealed; very similar to a new box purchase. The sensors came in an original Ring box with adhesives pre-applied. If the listing did not indicate Certified Refurbished I would not have known these were. The sensor was easy and quick to add to my existing alarm system. No issues at all!

I didn't realize that Amazon sold Ring products but will purchase them here from now on. They are cheaper than buying them from Ring even with my 10% subscriber discount and NO shipping charges. They work like brand, new, too ! Thanks, Amazon !

Reviewed in the United States on May 22, 2024
I needed a few extra units for a door and a few windows. I was so glad that you buy these separately and add them to you existing system. It is an easy and quick upgrade. If you need extra or just adding to you system I would suggest getting theses.

Refurbished or not, these work as well as the new ones I installed a few years back. Due to my configuration the sensors do not line up perfectly and this ended up being my issue with the original sensors over time. I could take the sensors off of the door, line them up really close together (1/16th inch) and they would work fine, but otherwise it was a no go. I am assuming over time these start to lose their effectiveness @ any range. Either way, I was having the same problem on two different doors and these refurbished sensors fixed the issue perfectly. Guessing due to my configuration I will have to figure something else out, or replace these every two years or so. As far as installation, just go into settings and remove the old sensor and follow the instructions on the app to add the new one.

5.0 out of 5 stars 1 of 2 was defective, but Ring replaced it without a hassle
Reviewed in the United States on September 7, 2023
I installed these on windows just days before going on a two week vacation. I started receiving low battery alerts from one of the sensors just a day or two into my vacation, and the battery died within a couple days of the first alert. I figured the sensor just had bad batteries and replaced them when I arrived home. I don't think more than a few days went by before I again received low battery alerts from this same sensor.

I did not want to remove the other sensor and thought Amazon would require I do so since these were a two-pack. I decided to call Ring instead, and customer service was great. I just needed to provide the SN on the sensor and customer service sent me a replacement. Ring wanted the defective sensor and emailed me a prepaid UPS shipping label. It does not get much more simple than that. Yes, I was out a couple batteries the sensor drained, but I had purchased a multi-pack and had plenty.

5.0 out of 5 stars Great for my mother
Reviewed in the United States on April 26, 2024
My father passed away recently and my mom is now living alone about 2 hours away. She was having trouble sleeping because of being alone and worried about someone breaking into the house. She wanted something simple and this was it. It took some time pairing and setting up all of the door and window sensors but once I got the hang of it the process was simple. I now can monitor from my phone if an alarm is triggered and if it was an accident I can help her shut it off using my phone. This was the case in the beginning but now she has the hang of it. It has given her peace of mind and now I am considering getting a system for my home as well. It would make a great addition to my current system which is just a hammer under the mattress. Definitely recommend

5.0 out of 5 stars Great with a few caveats
Reviewed in the United States on March 31, 2024
These sensors have been the most reliable contact sensors I’ve used (not with Ring, but with Home Assistant). Highly recommended.

A few other reviewers have mentioned the main issue: the sensor can easily fall out of its mount. I use double sided tape to hold them in place.

Another caveat for Home Assistant users is that I cannot get Nabu Casa to share this with Google Home.
