Have worried for our S3 me and my girlfriend this docking station. In my it was initially wonderfully - evening plugged ... the next morning it was full. Design like it - sophisticated design. After a few days it did not work - only to the charging cable directly, which can separate fortunately. When my friend the docking station worked from the outset not - always on the cord. Not settled by some wag ... fix. 2 times the same defect in a device - questionable.
