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.

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.

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.

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.

Dispatched from China so import taxes apply Order placed on the German website and payed in Euro. Claimed delivery time of couple of days, while in fact it is dispatched after one week from freaking China and I will probably have to wait weeks before delivered. This will add VAT and a handling fee when it is delivered, increasing the price with 40%. Complete rip off as the website clearly has the intention to hide this from the customers.
