Positive outweighs!

positive: - water can easily fill
Easy to see even in the dim light level -
- No measurable power consumption of clock and timer operation
- Coffee is very hot (switched off after 60 minutes)
- Clock and timer can be adjusted quickly

negative: - glass jug is too thin (calcified quickly) and looks quite cheap
- Increased cleaning efforts from glass jug and hot water spout
- Timer button flashes too bright (got the key taped)

Conclusion: still a good device if a more maintenance effort not interfere because of the price-performance ratio.
