I'm quite happy
Choosing a door/window sensor was aggravating to me. All the products seemed like either cheap junk or was a part of a larger system I had no need for. All I wanted was a product that makes a sound at a distant location whenever the door was opened. The reviews on this were mixed. The reality is that they do the job just fine. I like them. Can't beat the price BIGGEST DRAWBACK: sensors require a special battery I can almost guarantee that you don't have. The batteries that COME WITH the sensors may not last long, but once they do and you buy a quality replacement, like duracell or energizer, they will last just fine. Maybe I'll be changing the batteries once a year. Nonetheless the fact that they take an odd size battery is inconvenient, but inconvenient in 2023 is generally not that inconvenient. Second biggest drawback: There is a minor design flaw. You shift the cover across the base to expose the battery. If you install it upside down (that is to say you would shift the cover down to remove from the base) you can have an issue where it falls off the door when its slammed or if you have a very heavy use door AND the installation configuration necessitates installing the sensor portion holding the battery on the door itself. I imagine this would never be a problem if you installed the sensor portion on the door frame, which if you can, I'd recommend. If its on the door try to make sure that the cover does not slide downwards in the installed location. TIP: keep in mind the angle configurations you're working with. You have two pieces, the sensor and the magnet. They have to face each other to activate the sensor in the closed position. If you have the sensor on the door and there is no room on the doorjamb to place the magnet in alignment with sensor, you will have to chisel out a chunk of the jamb (had to do this on one door). The door is obviously flat and one piece will be attached to the door. There needs to be a flat spot opposite the sensor to attach the magnet to. Look at your doors and figure out your angles to see if these are a good fit. SOUNDS: A lot of comments on the sounds almost convinced me to steer away. Its is slightly hilarious and ridiculous clicking through the doorbell sounds. Some are very long. Having options like Fur Elise and Ragtime is just hilarious. Imagine hearing a MIDI big band song for 20 seconds every time the door is opened (lol). That said, there are a solid 5-7 very normal and simple chimes, you just have to scroll through and find them and that's an entertaining time I assure you. These full-on songs are so unnecessary and hilarious. MULTIPLE ENTRIES: The nice bit is that you can use different chimes for different doors, so when the door opens you know which door opened even though it won't be a voice that says "Front Door.... open" like some integrated systems do. ... show more

Good for sleepwalkers
Color: 5 Sensors + 2 Receivers White
So far so good, already useful. Bought for sleepwalking child, since he is really sneaky when escaping his room, and it works for that application! Haven't installed more than one motion yet, but seems fairly straightforward. Installed fairly easy, but needs to be installed pretty precisely to work, which may require some jimmy rigging on our other door frames with decorative trim. Biggest complaint is the ringer, even on the lowest setting, is a bit loud...I will be moving the ringer from my bedroom to elsewhere so it doesn't panic me quite so badly in the middle of the night. For the price, not bad. Are there better options out there, likely, but there are also worse. Middle of the road price, middle of the road quality, so not unhappy with purchase. ... show more

I’m sure the chimes is good but we decided it wouldn’t work for our situation so I will be returning them. The order was on time and delivered safely.

Serves its purpose
Color: 4 Sensors + 1 Receivers White
I liked this item for alarming me to the back sliding door and my child’s closet door being opened by the little one. There are only a few settings for how loud the chime rings and I wished there was a bit quieter option… I placed tape over the speaker to mute the quietest tone a little bit for times like when my husband or I step outside in the morning and the other is still sleeping. But overall satisfied with this purchase. ... show more

Work Great
Color: 5 Sensors + 2 Receivers White
These sensors work perfectly. They are shipped with the batteries in place and paired to the chime. Incredibly easy to install with extra stickers if needed. I like the off/on switches so the sensors can be turned off when no one is home, or no little ones are present.

It worked and then it didnt
Color: 4 Sensors + 1 Receivers White
This was a 5 star item until a few days ago. We bought it to let us know when the child opened a door and after 2 months it no longer works. The door opening triggers the plugged in speaker but only the lights go off on the plug in, there is no sound. What good is it if there is no sound?

It did not last long. Ringer stopped working. Door monitors did not work consistently. Sometime they rang for no reason.

This has been amazing and life-changing for my family
Color: 4 Sensors + 1 Receivers White
I’ve been looking for something like this for years and it exceeded my expectations. If you have a loved one with elopement issues or lacking safety awareness, this is totally worth the money. I’ve tried others in the past and none of them worked out and I wish I found this years ago. Don’t hesitate to buy this if you’re on the fence. ... show more
