POSITIVE
The clock displays the time. Even properly if you do not again inadvertently corrupted the time zone (see below).
The alarm clock wakes.
NEGATIVE
Really only for singles to use. Each keystroke is acknowledged with a loud beep, even if you turn on the lights only with the SNOOZE / LIGHT button. I do not always wake up my partner, if I'm awake at night and want to know what time it is.
The key assignment is a mess. Which genius only came up with the idea ALM ON / OFF and the time zone setting (-1 / 0 / + 1) on one and to put the same key? It took me a few minutes to find out that this button is designed as a rocker. In the manual there is nothing to it. By pressing the button on the left edge, can the alarm switch (Off / On / Snooze). By pressing the button on the right side, you can set the time zone. Once was not paying attention and already has one, instead of the clock turn, adjusts the time by one hour. Undocumented: Hitting the button by accident in the middle on one to the display of the time on the alarm time, and vice versa (exceptionally without beeping). On design the rocker function reveals not necessarily, the keys act as normal buttons and the center button is also not designed as a rocker.
With my old alarm clock I had a relatively large display in the lower right corner, where I could see whether the alarm was turned on or not. In this clock the lower right corner is occupied by the temperature display. The alarm is indicated by millimeter large icons in the upper right corner. With sharp eyes and sufficient to detect light well, but only then.
The lighting is a joke, a single green LED illuminated funzelige from the center below the display panel. That was my old alarm clock though not much better, but at least without loud beeping.
The manual is a joke. When you have figured out how everything works, one understands the operating instructions. Actually it should be reversed. The font is tiny and hardly legible for the elderly, no wonder with six languages on a double-sided A4 sheet.
CONCLUSION
When an alarm clock under 10 euros I expect neither top quality, nor any sophisticated functions. But (Set alarm, activate alarm) the basic functions must be as simple as possible, and at a glance you should identify which alarm has been set, and whether the alarm is activated or not. The operating instructions should be read and understood without a magnifying glass. All this is unfortunately not possible. I give the product in spite of these shortcomings, two stars. After all, it displays the correct time and wakes up reliably.
