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.

X-Sense Smoke Detectors Purchased two Smoke Detectors from X-Sense to replace two expired Smoke Dectectors. They both failed in six months. Would no longer pair and when I checked with a smoldering fire, they did not go off. I sensed that they probably never worked as a smoke detector, because there has been smoke from the Kitchen and the Fire Place, and nothing sounded. The older smoke alarms would have gone off right away. When I contacted X-Sense, they said they should not be checked with REAL SMOKE! WHAT???!! Save your money and time. These things are JUNK! Buy from one of the major makers of smoke detectors.

Shipped from China and customs duty is payable on arrival in destination country. Ordered X-Sense camera from the German website. They telephoned to say only available with US plug. That was OK for me. It took 25 days to be delivered from China (so the EU web site is rather misleading in that respect and should be more transparent). I was required to pay a customs tariff (in Spain) plus 21% VAT on the tariff. Total of 7.69 Euro so be aware of this additional cost which I assume will vary according to the destination country.

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.
