X-Sense Smart Smoke Detector Fire Alarm with Replaceable Battery, Wi-Fi Smoke Detector, Real-Time App Notifications, XS01-WX, 1-Pack

This thing is so small yet works. I like that it's connected to my phone. I worry something will happen when I'm not home and won't know. I had it go off once from my wood fireplace and it worked. It beeps and notifies your phone. It was easy to install.

Very good. It was easy to connect and the test immediately on my cell phone. A minor peeve, if the mounting screws are installed level, the unit itself is just a few degrees out of being perpendicular.The instructions were complete and gave a range of acceptable mounting dimensions.It works! Had it on the kitchen counter before I mounted it on the wall, when I exhaled the vapor from my vape, it set it off and it sent a notification to my phone. I am highly confident that I will receive very timely notification should fire erupt in my house.I intend to purchase several more for optimum coverage of my home.

Just received it today and set up went great.I noticed the video reviews when i was purchasing but im not sure those people understand how fire alarms work. There is a photo sensor inside them and when a certain percentage of light is blocked out the alarm goes off. One guy had no smoke, and the other guy had a tiny stream outdoors. Its hard to get smoke alarms to go off outdoors unless there is heavy smoke. Dissipates too fastTook the smoke alarm to unfinished part of basement (my workshop) so i could test with a cigarette. This way i could easily exhaust fumes with fan when done.Lit up cigarette and began setting it up. Alarm went off unexpectedly. Wasnt even blowing into it. Then after set up i blew smoke in and it went off.They work great.Reason they go off so easy in kitchen is because smoke from food & grease contains large particles which block the sensor easier, so try not to set up directly over stove.Love this alarm. You can invite up to 12 family members to be connected, so everyone will get the alarm notification, even if theyre not in the house, as long as your wifi is working.Alarm has a volume level too, which is cool. Its pretty loud even when not up all the way. Of course you should definitely have them up all the way.Its small too. Can easily be palmed. Very easy to mount with 2 screws that come included. They use a CR123A battery (as opposed to 2 AA batteries which is normal in U.S.). So id order a few CR123A, because you probably dont have them lying around. Id also suggest buying a better brand, as this one is already down a bar.Definitely going to order more of these alarms, and some batteries

Sensible low profile fire alarm. Extremely easy to set up and place into use. Easy to understand instructions with equally simple ceiling or wall application. No specialty batteries required so no need to worry about replacements. It's small dimensions don't distract from room furnishings or decor. It provides the entire family reassurance of continuous fire/smoke monitoring. Alarm is loud enough to wake any sleeping person. Brought more for myself and sent some to family members.

These little alarms are great for tight spots like attics or crawlspaces. They connected quickly and easily and give peace of mind in less traveled areas of the house. It's easy to check on them via the app and to get notified if they need batteries changed. Haven't had a true use for them and hope that I don't, but they seem like a quality product. They appear to regularly run through a self check, too.

2nd Smoke Detector:After ordering a replacement smoke detector, because the first one wouldn’t connect with the Hub. The second smoke detector would not connect with the hub. My Wi-Fi works great. My Bluetooth worked great. The QR code didn’t work. I contacted X-Sense for Assistance and received a reply that they were out of the office for three weeks. That three weeks would’ve been past the return window. So their customer service was nowhere to be found as they actually shut down the company for a three week vacation. I was left with a smoke detector that would not connect to the hub. If I wanted to stand alone, smoke detector, I would’ve bought one. But the point of having a smoke detector connected to a hub, which is connected to Wi-Fi, so that I could be notified if there would be a fire in my home when I wasn’t there.My suggestion, find a different brand.1st Smoke Detector:The smoke detector was not ready to use as it came with a 100% dead battery. I will be ordering the battery that I need and hopefully in a few days when I receive them, I will be able to try to connect and use my new smoke detector. So if you decide to purchase this, make sure you order CR123 batteries at the same time. After installing the new battery, after at least a dozen attempts, they smoke detector would not connect with the hub.

We have existing hard wired smoke detectors in the house. Having something that can communicate to my phone provides better peace of mind. I haven't done a smoke test, but let's hope we never have to cross that bridge if these in fact do work while powered. The smoke detectors came packaged well. It was a little difficult to remove the back cover. Battery was already installed with a strip that needed to be pulled off. Getting these mounted was a breeze. The app took a little getting used to. Particularly around the naming for the devices, home, etc. So far so good. I notice that every now and then it will rapidly blink blue for about 5-10 seconds then stop. Not sure if it's just confirming/establishing a wireless connection?

This smoke detector is a Winner! It's small,Reliable, Has Wifi App, And at a great price! It will notify you if it is triggered with an alarm and status on your mobile device which is what i was looking for & at a great price.
