The housing is made of simple plastic, had from the beginning two paint damage. The movement and the internal processing are very easy. The seconds clocking is set very inaccurate. On some days you lose grip even times a minute on the clock, so you have to adjust all three / four weeks once. The clockwork, incl. Display is slightly movable under the plastic cover on which the blue light cylinder sits and the auto switch is not mounted in the Exterior, so that it can move freely.
There is for blue light fans a little eye-catcher and the clock works so basically even. The service is a bit strange in the beginning, when you have to get out there sometimes it also works. But we must also ask to high expectations of the quality for the price none.
I'm at least very happy about it, as I was given them.
