The device fulfills the function that it has. Much more one should not expect, because the processing is not exellent. The Verklebeung the 2 switches had totally resolved (what could possibly have been because of the cold during transport), as evidenced by a rattling inside the box. But for the low price I took a screw and bonding by means of hot glue gun in purchasing. Now there's nothing left to complain, I hope that the device works well long.
