Goods will be delivered fro China (customs, tax and duties apply) Thy run a shop de.x-sense.com in German language pretending the goods will be delivered from Germany or at least from Europe and payments will be in Euro. After purchase in Euro payment is swscued fro the credit cad in US-Dollars adding around 10% bank charges. Then they send an E-Mail saying that the are sorry for no goods beeing in their (fake) german warehouse and that goods will be delivered within 4 weeks time directly from China. They do not mention that customs (20% from purchase amount) and import-tax (19% from purchase amount) plus customs service charge of 15€ will be on top when receiving the delivery from China. At the end the goods will be at least +49% of the prices shown on the webpage. They do not respond to E-Mails. The invoice they send does not comply to any european tax regulations. Recommendation: Do not order on this page. If you think you need their products order at a european store which has an Imprint and contact information and a european tax-registration number (VAT-Number) and who ships from germany and

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.

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.

do not buy I have tried to connect the base station to two seperate routers without success. Also I have tried to enter the information manually but the app requests a QR code or serial number but the base unit is blank with only the model number on. I have also entered the wifi password but the unit was unable to connect to the router although my phone and tablet were able to do so at approximately 30 cm away from each other. This equipment is poor quality and not worth the money avoid!
