Device reasonable, unfortunately very little or incorrect description

Description partially deficient (battery NOT! Possible, batteries are only for time / channel memory retention in case of power failure). Knew this before, but just is not right and should be removed from the item description.
- Display illuminated from 05:00 bis 22:59 clock throughout (darkening virtually unnoticeable) If it interpreted almost as a defect and am only come out that this is "normal" for investigation.
- Provider offers selbes device slightly more expensive with other manufacturers name (Amazon). Something strange. There, however, he writes of a great self-shutdown of the display during night hours. So I came out that's not broken my device.

Conclusion: Would the wrong indication of the battery and not the Note on display in this product sensibly be led (continuous light is not 100% my case) gäbs more stars. Nevertheless, price / performance right!
