X-Sense XS01-W causes false alarms around the clock I bought 10 X-Sense XS01-W connectable smoke alarms and (after testing) installed these in a student home. Within a week, I got reports that these alarms went of in the middle of the night for no apparent reason. A week later, I witnessed this myself: I was in the house on saturday morning and all alarms went off, one after the other with a couple of minutes in between. The trigger each time seemed to be a different alarm. I took all of them home and put them on my desk. Within the day, I had the same experience (luckily not at night). I retested all of them, and found one to be defect (ie it did not react entirely as described in the manual when I tested it). But regardless of that, I think it is unacceptable that any defect would cause this behaviour. I luckily was able to return them, and now bought non-connected alarms again.

wowww 1 month later ship from china… wowww 1 month later ship from china wowwwwwwwwww.

X-sense WiFi smoke alarm that does not work My problem is with a smoke alarm which is marketed by a company calling itself ‘X-sense’ the alarm purports to function wirelessly, it does not, I have contacted the company for help but have just been fobbed off each time. I was going to review them on Amazon which is where I bought it but they, or Amazon, are blocking reviews hence the review is here. According to what I get on Amazon X-sense do not exist, no doubt another of the Chinese sellers who disappear when they get enough complaints and Amazon do not help as there is no way to contact them.

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.

Purchased a carbon monoxide/smoke… Purchased a carbon monoxide/smoke detector after five months battery is now flat, contacted x sense and despite a commitment stated on their literature to respond I am still waiting.
