I bought this screen, because I had the idea really liked the LED! The screen is a real eyecatcher and attracts attention, even on helligsten day you can see the LEDs. But space is rather only for one person, unless one imagines closely. In Dunkelen Logically, the light function is best to wear. The shield has three modes: 1) off 2) flash 3) light to 1: unspectacular, everyone knows. In addition, the other screens can be used for a fraction of the purchase price. to 2: Here go a few LEDs to light up 3 seconds to be replaced by another group LEDs. The effect is surprisingly good, because it acts as if you had glowing raindrops on the screen. Or. it acts also as if the screen respond to the water and light up at the places encountered by the rain. Looks really great out! to 3: When all LED are turned on, the light bright enough to the dark the way to better recognize a bit. It does not replace a flashlight, but if you want to unlock your front door in the dark at night, this function is already helpful!
As regards the issue of security, I had been many opportunities to test the screen. It works reliably, is dense and is very well perceived from afar. Whoever crosses the dark a road should hereby be better recognized. Overall, a fun gadget, in which a variant for 2 people would be welcome too!
