    These are standard alarm door sensors. However they are slightly larger than others. With the larger size, you slightly more distance to play with while still keeping them activated. Very easy to install, comes with command strips style tape and a mounting bracket. You choice on tape or bracket. Overall a good product.

    I purchased the Ring kit and needed just a few extra sensors for all my basement windows so this was the perfect amount to add, even slapped one on my exterior door into garage. So easy to install and setup, I just used the adhesive strips on all my sensors and they are stuck solid! Great product.

    Ring is great buy your own equipment and have no monthly fee if you want or a small monthly fee for monitoring. Very easy to do it yourself and the equipment is reliable no issues after more than one year. Cameras work very well and everything is in one app!

    Ring Alarm

    The Ring System is a DYI system that is pretty easy to install. If you have basic handyman skills, you should be done in no time. The monitoring service is inexpensive. I have many systems installed on my properties but think I will be using Ring from now on. The app allows me to Arm and Disarm the alarm and offers a lot of options for setting up users. Only drawback is that you need an Internet connection, which is a monthly cost from your service provider. I use it on my investment properties but, if this is for your own home, then you probably already have service, so it is no issue. It is simple and straightforward and I have to give credit to the support at Ring, they have been awesome.

    No issues so far. Bought these to do more of my house with Ring Security. Very easy to install and to connect to the rest of the security system. Haven't had them long enough yet, but the battery seems really easy to access and swap if it ever dies in the future.

    Not much to say here; they are extra sensors for the ring alarm system. They do what they are intended to do and install easily. They are a little on the larger size, but I didn't have any issues putting them on doors or double framed windows.

    I have the whole Ring system and its not bad! Great price compared to others such as Vivent! Uhhh was paying 59 a month for like 4 years and got fed up! This product is decent and wouldn't trade it! Easy to install but one day I accidently opened my window and pushed against the device and well boom it came off so I just had to put it back on, problem solved. Its worth the money.

    Installation was very straightforward and setup with the app and hub was very easy. I was pleased there were options for mounting. Fyi, I dropped one and it read as "tampered", but after removing and replacing the cover it reset without issue

    Very easy installation. Very forgiving on abnormally shaped windows, without giving up functionality or security. Accidentally forgot that they were on the door and when I opened it, it triggered the system right away.

    I bought the home ring system as we were traveling abroad for 9 days. The system was affordable, quick and easy to set up and provides a free initial 30 day monitoring optionally followed by a $10/ month charge for monitoring or even less $100/year. The system includes cellular back up and provides a smartphone app that allows 24/7 access from anywhere. This package of sensors were an add on for coverage on all windows and doors in our home. Again, you can add additional motion, noise, and contact sensors or cameras as needed. And if we move, it can all be relocated with minimal difficulty. I recommend this system as I have been more than pleasantly satisfied with everything about it to date.

    In my experience these were the perfect size for my doors but a little bigger than I would have liked for my windows. Regardless they are extremely easy to install & even to set up/pair with the Ring alarm system.

    I have had the Ring alarm for over a year. I purchased this pack of 2 for my garage doors. They work perfectly on install and the price is great considering even generic sensors I bought for Samsung Smarthings was about the same price each. I need 1 more and do hate that you have to buy 2. Also batteries are still good after 1 year.
