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!

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.

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

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

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.
