The clock on the screen differs from the actual clock: the screen is incredibly small, under one inch tall. The resolution is so low that even my Nokia 3210 could show on a screen - and neither is the exaggerated representation nor defamatory. It is a fact! I could count with the naked eye the pixels, so low is the resolution. There is so little space available that even words with only four letters in some menus may not be fully displayed. In sunlight, but this does not matter, because then you always can read nothing at all (screen incredibly dark)
I can imagine that some satisfies this clock - to me but not for one second. That the clock is also charging without power supply as possible with a simple USB cable is the only consolation.
Keep distance of this clock, and the manufacturer: please endeavor not to write the product description so that a completely false picture of the article is created, just to get more copies over the counter.
