The product replacement via Amazon was exemplary. A really great service with rapid turnaround time.
The second clock now hangs a few months with me on the wall. The wireless operation works. The switch to winter time ran automatically. There's a star!
Not meaning of a clock, it should be admitted that it will stop just for hours, thus indicating permanently completely wrong times, and at some time over the radio function set right again. To her read the correct time equivalent, because already more a lottery.
The clock I trade now again. At the same time I made a request to the manufacturer to see if there is a possibly defective production in the entire series. A response is pending.
Addendum: My request to manufacturer unfortunately remained without answer, what I feel pathetic and that's why this manufacturer will hide in future purchases and referrals.
