Ordered 11/02/2021, received 22/02/2021. At the opening, the detector had no screen protection, however, it was clean and without scratches. The charging cable was not attached, but the plastic fastener was present. Is it a return that has been revised, repaired? For the moment, it is working properly.

Commandé le 11/02/2021, reçu le 22/02/2021. A l'ouverture, le détecteur n avait pas de protection d'écran, néanmoins, il était propre et sans rayures. Le câble de recharge n était pas attaché, mais l'attache plastique était présente. Est ce un retour qui à été révisé, réparé ? Pour le moment, il fonctionne correctement.

It is so convenient that we can recognize the timing for ventilating air in the crowded room by use of this machine.

I recieved the carbon detector on 22th December 2020 . Product ID 1742340, Order NO. 93637782. It was working until January 5th 2021. Now it stayes all the time by 400 ppm. I would like to return the item and to have it replaced to one which is working. Thank you. Kindly Angelika Kornfeld angiekornfeld@yahoo.de
