X-Sense Mini Smoke Alarm, 10-Year Battery Fire Alarm Smoke Detector with LED Indicator & Silence Button, XS01

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.

I love the small size of the product and they are very loud

This smoke alarm is really nice and small

A very small but very loud. This is replacing one that I had for 2 years with a 10-year battery. Problem with that one is it gave false alarms, and it always seemed to be at 2 in the morning. Hopefully this one will do the job. If I have any problems I will update this review.

Good

easy installation - clear instructions

**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.

Small profile. Works great
