Delivered is a hat-trick of the smoke detector GIRA Basic.
When the basic product photo, you might think that it is high-gloss Kunsstoff - which is not so. The smoke detector is designed in matt, simple plastic.
By design, I find the control panel is not so well - revealed here that ultimately the same technique tinkers in smoke detectors, as in any ordinary smoke alarms. There is a test button and the familiar red LED that flashes every minute when the smoke alarm is in operation and functioning properly.
The flashing of the LED is really short and very discreet - in the bedroom I would still nervous.
Visually, the smoke detector does not fit at all switch series, is dull and simple by his touch and feel her too cheap. Although the supplied color is referred to as "pure white", one can in good light even find a stitch to Vintage White (for smoking apartments mags fit). The Gira smoke detector basic and therefore this hat-trick I would not buy more - and send the detector also back.
Unfortunately for those who value design and fine workmanship, the price must enter a bit higher - uses all nix.
PS: Looking at the other reviews I would say: Smoke detectors are a very important thing and belong in every household ausnamslos. I can also imagine that the standard technology built their service providing good. My concern here only around design. I have uploaded two pictures that illustrate the addressee.
