    Works well once setup

    The ring alarm and ring sensors work very well, and for most they install as intended. This review is written for those of you that may have an install that doesn't work as intended. A few things ring should make loud and clear in their install docs. 1. If you buy multiple sensors absolutely do not pull any tabs or turn any sensors on until the last item you installed has completed. Give it a few minutes to be certain. The ring base is easy confused by 2 requests. 2. The app can be flaky. Change your phone timeout to never while installing. Several times on my s8 I had to start over because the screen turned off, and even though the last screen I was on came right back the app flaked out. 3. If a sensor doesn't immediately connect after your first try DO NOT try to add it again. Reset the sensor. Wait a few minutes. Delete it from the base. Chances are it communicated with the base and the base is in a weird state with that sensor. 4. You may have to reset new sensors, and then pair them manually. Even if you never attempted to pair them. 5. Before attempting to install any add ons outside of the base package of equipment that is pre paired for you, become familiar with resetting each component completely. I suggest printing out the guide to resetting them. The keypad and the base station are the most difficult. Ring support asks you to call them to reset the base anyhow and for the average user I would agree. Once I diagnosed the issues with mine and determined the base station was having an issue correctly pairing the devices I hard reset all of my equipment. I then added each piece manually and waited several mins between each piece to install the next. The system has been working great since then. Pro tip Most doors aren't flush. This causes mounting issues with the sensor. The slim part is simply a magnet encased in plastic and is easily removed. You can just mount the magnet which will mount inside nearly any door and trim and allow you to line things up.

    Had this for 5 days and it’s been solid. The setup was very easy and flawless. The quality of the keypads and base station is nice. The keypads speak the status when activated and also serve as additional sirens. The base stations chimes are nice and loud as is the siren. The app has been responsive. This is a great deal especially when you factor in unlimited cameras with 60 days of saved video footage and 24/7 professional monitoring. My home insurance discount for a monitored alarm makes this basically free every month since this service is only $10 a month total no contract. The only negative so far is the lack of third party support, automations and geofencing. Also the door/window sensors are a little too large. I’ve tried Nest Secure which is more expensive equipment, $19 a month on a 3 years contract! Plus at least $8 a month for two cameras and 5 days of 24/7 footage. Also the monitoring does not include fire even if you have nest protects! The base station is not loud enough and you can’t use another base station or buy extra keypads or sirens. Also tried SmartThings/ADT system. Decent system but monitoring is $35 a month including fire. Automations are broken and Smartthings has been down a few times this year. You can’t buy multiple keypads or sirens so you just have the one.

    Garbage

    The Ring Alarm System has been the worst purchase I have EVER made. We purchased 5 motion sensors , 38 contact sensors, range extender, base and keypad. The base has recently stopped connecting to our wifi, yet shows that its still connected (app will not connect to base) and the contacts randomly drop offline. We have a 3 unit orbi ac3000 system so it can't be wifi as the signal is strong all the way around our property (0.7acre) and in every area of our home. This is unacceptable for the cost and application. I cannot trust this system to adequately and reliably serve as our security system. I wish I could return this garbage but our return window has passed. Had a wireless ADT system in our previous house that never gave issues. I highly recommend avoiding this product.

    Easy to install and add to existing Ring alarm

    These are just like the one's included with the Ring alarm system when you get it. They install the same way within the Ring app. They can be mounted with the included screws or with the included sticky tape. I will that one sensor fell off my back door when I moved it to re position it during install. The tape is meant to be pressed on and not moved. If you do need to re position it then just use a new piece of tape. I ended up getting a different and stronger double sided tape to use and just cut it to shape. No issues with it falling off now. None of my other sensors have had issue with the included tape though, so don't be afraid to use it. As a note, you must have the Ring alarm to use these sensors. They will not work with the Ring alarm base station.

    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.

    Great Contact Sensors

    I bought these as additional contact sensors to the one that was included with the security system. Unless you have only one door from the outside, you will need additional sensors for adequate detection. One thing I did discover since I placed these sensors on my doors is that they will still function properly even if you have odd door molding as I do. I discovered they do not have to be exactly lined up (except for the marked lines on both sensor pieces) or flush to properly function. I thought I was going to have to chisel out some of my molding for them to function properly, but I did not.

    The Ring Alarm system is well thought out and easy to install. The Ring contact sensors are very easy to pair with the Ring alarm. The seem to have pretty good range. Pricing on these is very competitive. At $20 each, these z wave plus sensors are cheaper than just about any comparable sensors on line. The Ring alarm works with some other brands but it is hit or miss. Even if they do work, they may only indicate status and not trigger the alarm. Ring has made the right decision to make their contact sensor cheaper than others.

    I had 2 sensors out of the 12 I purchased not work properly but Best Buy replaced them with no problem. Overall its a good system and nice sensors. They are larger than competitor sensors, SmartThings, Iris, but I assume they will have a better battery life. The magnet part is too large to fit on the window so we used the older Iris magnets instead. You have to connect one sensor at a time unlike Iris where you could connect all the sensors at once.

    We really like our ring products. The sensors are easy to set up. Pull the battery tag, link it to your phone, stick it on the door/window. The noise the base station makes on opening/closing is customizable, but we really like the default sound. Some people say the sensors are a little big and I can see their point, but I didn’t have any problem with it and hopefully this means it’ll last longer because bigger battery = longer life.

    I've got about 10 of these around the house - the most recent was the one I put on my gun safe to make sure I knew if anyone accessed the safe when I wasn't around. Out of the 10+, I've only had one that was outright defective. I did have one that need to be reset - but you don't need to call customer service to do that, just follow the instructions on the app. Overall, it's a solid product and I would (and will likely) buy it again.

    I’ve been very satisfied with the alarm system and love the fact that you can add to it at your own pace which is what I did with these two sensors. I am convinced once word gets out the ring alarm is going to put the other companies out of business. $10 a month for hundred dollars for the year for professional monitoring is unbeatable. The alarm itself does everything that you would want an everything every other alarm on the market does.

    I bought this 2 pack of sensors to put on the master bedroom windows. I’ve had the Ring Alarm System for about 8 months now and absolutely love it! Not only was it easy to install, but its very user friendly but very secure at the same time. As for these sensors, they are so easy to install it isn’t funny! Plus, you can customize the notifications and chirp tones. I highly recommend!!!

    It feels strange rating contact sensors. Because they either work or they don't. These work just like any other contact sensors except they feel very sturdy. I have other contacts sensors from other manufacturers, and these are definitely more premium. I sure do hope so because they are so expensive. they all communicate properly with the base unit no matter where they are in my large house.

    The ring setup is pretty straight forward. That being said they provide subpar hardware. It can take several tries, resets and much frustration trying to get them to connect using Ring's own setup software. This latest piece will not connect at all. My "ease of use" rating below is in reference to the everyday use of the Ring system.

    Ring window/door sensors

    These contact sensors do the job. I needed to monitor two additional doors so I ordered these as they werent in stock at any of my local stores. They were just as easy to set up as the rest of the sensors and function as they should. These are a great addition if you need to monitor additional doors or windows with the ring security system.

    I purchased additional sensors to go with my Ring Alarm system because the system I purchased had only 4 sensors and I needed more. The system immediately recognizes the sensors when activated making installation a breeze. They come with 2 sided tape & screws depending on your installation requirements. So far I am very happy with the Ring Alarm and it’s components.

    Do not work with molding

    The contact sensors do not make a connection if your door has molding around it. I am working on my own solution but it seems Ring should have already figured this one out. Lots of postings on line with others having the same problem. If Ring is not responsive to something so basic makes me worry about the whole system.

    Ring has made their home security products easy to install and set up. The Contact Sensors are no exception. You can hang them up with the included 3M strips or use the included screws. They also work well and don't have to be extremely close for them to work. Inside the ring app you can label each sensor so you know which location is opened when it happens.

    I LOVE RING ALARM and alarm contact center.It has been working great! Took me a little bit to get used to turning it off before opening my doors but I love that you can arm or disarm it through the app on my phone!!! I ordered the professional monitoring from them too for an entire year! Just a great deal all the way around

    Better than your average alarm sensor

    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.
