Ansich the clock is very nice, about 2 weeks, then it dissolves. They do not last forever was clear at the price, but with a year ago I would have expected ;-) Since there is no invoice was attached to the envelope of the sender, I got a notification from the customs that I should bring everything I have of invoice and order and pay and then I can pick up the goods. A tear expenses for the clock, I also never again. The sellers were nice and quick contact, but the effort is not worth it for me.
