IT INFACT WAS COLD SOLDER JOINTS, THAT LOOKED LIKE A CIRCUS MONKEY or they let loose a 5yr old with a soldering iron.AMAZON PACKAGING FOR SHIPMENT HAS GONE BY THE WAYSIDE, INSTEAD OF INCASING THE PRODUCT ALL THE WAY AROUND, THEY PLACE IT ON THE BOTTOM OF THE BOX & PUT BROWN PAPER ELSEWHERE. NOT MUCH PROTECTION FROM SHIPPING. One cabinet corner was smashed !
