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

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.

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.

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.
