X-SenseMini Smoke Alarm, 10-Year Battery Fire Alarm Smoke Detector with LED Indicator & Silence Button, XS01, 6-Pack

You won't sleep through these! EASY to set up. I already have a set of 5, but have a 3 story, 15 room house with an attached studio. I will warn you, I don't see getting 10 years out of these batteries, and 2 of the first ones have already gone dead. So just know that.And then, for reasons I cannot understand, someone stole two of them. One was the dead battery so that joke is on them, but still...So I am adding 3 more. I love that they all connect and work together without having to have expensive hard-wiring done. If the alarm goes off in the back room of the basement, they ALL go off, all over the house. Now, I haven't figured out if they somehow can indicate WHERE the fire is, but having survived a terrible fire in the kitchen while I was sleeping upstairs in my room over the sunroom (which pretty much is almost like not being in the same house because it is so remote), I wouldn't hesitate to just grab the dogs and get out, and worry later about WHERE the fire is. Had it not been for my little Pom, none of us would be here today. At that time, I had the regular First Alert alarms, and I didn't hear it go off at all. But Quiry did and she got me and the rest of the pack out.Right after that, I bought a set of 5 of these. I like that I can test them all at once, with the test button on any one of them. The low battery pings just like the regular 9V alrms, which I was not expecting to hear for another 9 years, but...I have not priced new batteries yet, but something tells me I might swallow my tongue.Over all, though, other than the disappointment in those 2 batteries, I recommend these alarms to anyone. They are ear-piercingly loud, they are very compact so you won't have those unsightly 6" discs hanging over the doors or from the ceiling...most of mine are concealed almost completely by the oversized woodwook in this 150-yr-old historic home. They are very smaill. If you have a large house, I cannot recommend the wifi alarms. Especially in a multi-story home. If a afire had started here in the basement, and all I had was the old-school alarms, by the time I knew the house was on fire, it would be too late to get out.With these, that will NEVER happen.

Product arrived on time in fact, it arrived early

Smaller then expected,,,,,easy to install and love the 10 year battery!👍

No está mal resuelven

very compact. easy install!

Works as it should, easy install to wall.

**WILL UPDATE IF ANYTHING CHANGES**Ok, let's start with the positives. (Skip to the bottom for a short summary)- very small and compact• the design does not bring attention to it and takes up minimal space they look "cute" as the girlfriend would put it.- lightweight, easy to install• when installing into drywall its recommended to use the anchors but I didn't find it necessary because of how light they are. Just 2 easy screws!- functionality• Very loud! Which is awsome, louder than my old system for sure.- affordable• for the price you can't beat all of the positives come together for a beautifully designed productThe negatives (oh boy)1. It seems to me that they make these and let them sit on untill they are sold, and may not test them before they send them out to the consumer (you). While the ones that work work great i ordered the 6 pack. 3 of them seem awsome and I have not had to use them, knock on wood (metaphorically), the other 3 not so much. 2 sound like they are already on the cusp of dying and you have to click the button repeatedly for the test function to work which makes me nervous if they will work in a real situation. And last but not least the final smoke detector is functional but the speaker sounds blown. Not ideal for something that is designed to wake you up in your sleep.2. Customer service. I contacted the company directly via email to let them know of these issues giving them my name and order number so they would have no issues looking up that i was a verified buyer. Anyways I contacted them on Thursday I have yet to hear a response (2 buisness days) its now Sunday with no response 4 days total. That being said if I do hear back from them and they offer a solution I will update my rating untill then it seems ive got the buy 6 get 3 working deal. And I'm not comfortable with that!3. Short one, I promise, you can not replace the battery the entire unit needs to be replaced.Sumed upPros.• lightweight• easy to install• compact design• loud (kind of, see cons)• affordable (kind of, see cons again)Cons.• some came damaged• customer service? Don't know if they exsist.• battery life is questionable• no battery replacement, entire unit needs to be replaced.*updateBOOOOOOOit has not been 10 years (advertised as battery lasts 10 years) and all of them have died. Would not buy again would not recommend don't buy this product.

They tested fine, hopefully they also work when a fire breaks out. IF that is. Hopefully not tho, but if it ever happens I will get right back on here and let you know.
