The items were as always promptly delivered through Amazon. As other reviews it can be seen, there is now and then a false alarm of a smoke detector; so also with us. However, the seller does not want mobile phone Now take back the defective smoke alarm but the complete set. Other reviews can be found in that other customers have again more defective devices. To avoid this we just wanted to replace the defective device. A direct demand from the manufacturer has shown that this is possible without further notice. We will accept the offer and replace the faulty detector.
Conclusion: good product, good service by the manufacturer but not at Handynow.
