This Company may be a scam - AVOID!! I'm not sure if this company is a scam. I ordered a CO2 detector which has never arrived. The tracking information I received directed me to a shipping company website in Chinese and I had no ability to change to language to English. I have sent e-mails and called customer service numerous time with no response - AVOID AT ALL COST

Good Smoke Alarms With Plenty of App Features We recently bought eight X-Sense XS01-WT smart smoke detectors & three of them have gone offline which should not be a problem. However, after going offline they have failed to reconnect to the router. Customer services did respond very quickly with advice on how to reset them & one detector did get back online but the other two won't & they don't respond to the button presses & beeps outlined in the guidance. UPDATE:The instructions were quite poor & didn't cover what to do if they went offline. Eventually I found, by trial & error, that if they go offline all that's needed to bring them back online is to press the test button for a second. The unit then goes back online & sends a notification to my phone.

Useless I bought a "10 year" smoke alarm through Amazon which failed after 18 months. Following Amazon's instructions I contacted X-sense numerous times but they ignored me. I then complained to Amazon which refused to help because they only "fulfilled" the order, Be warned about this company and about anything that Amazon "fulfils" - they will leave you high and dry.

Customer Service Non-Existent We ordered two smoke and carbon monoxide detectors (built-in) that worked fine for a few months. All of a sudden, the two started going off randomly and would also go off during the early hours of the morning. You can imagine waking up to them both going off at 3am! I contacted X-Sense directly for advice, as i cannot turn them off without permanently deactivating them. It's been two weeks, and we still haven't heard back from them. It was quite urgent as they kept going off all day and night randomly. I cannot honestly recommend X-Sense as the customer service is non-existent, and the products, well, what can I say.
