    The electric part works good, but the design is problematic because of very few holes. However it is possible to modify them by making more holes like I did (pictures). This will make it a lot more sensitiv to smoke of course, giving you a lot earlier alarm (by many times). If your having it in the kitchen on the other hand I'm sure it's good enough as it is, since then you do not want it to be too sensitiv. But otherwise I strongly recommend drilling more holes in it.

    The design has to little holes in it, making it a lot less sensitiv. I drilled some holes in it over the detector side (you can drill on both sides if you think that looks better). This makes it go off many times earlier, potentially saving your house and your life. Other than that the electronic parts seems to be working fine. You just need make more holes in order to help the smoke get in to the black component (detector component).

    Что делала служба доставки с посылкой даже не знаю. Упаковочные коробки поврежденные, в одном сигнализаторе что-то болталось (это оказалась выскочившая со своего крепления пищалка). Сами сигнализаторы рабочие, пищалку на место поставил и все проверил. Пищат громко, чувствительность

    Zle balenie od predajcu. Krabica príde poškodená. Detekuje čo ma ale opozdene. Nutne dokúpiť 9V batériu.
