My Shield controller's fucked, the directional pad stopped working, and had to buy a wireless keyboard. Logitech K400 plus, I'm lovin this thing tho. Shield system blacks out for a split second, and then comes right back, about every couple hours or so. Pain in the ass during a battle scene or something. It's probably because I bought one of the very first ones, at the first release. The new ones now I'm sure have been quality enhanced over the last year, ironing out some bugs. Plan to get a brand new one, maybe the next time they drop/sale...
