Arrived on time .. but few downsides ..

My order arrived earlier than expected (within a day), it works, as is well illustrated.
But flat bill is in German .. So no top for a return, or anything except for people who understand .. And I paid in addition to shipping costs (probably because it comes from Germany ..

If it works, I struggled a bit to find how it was to synchronize. But she seems to respond well .. Otherwise the shipment was secured, the package was well packed! I hope my review will be helpful to future buyers.
