So far I honestly haven't had a single problem with the case at all
The plastic is TPU (Thermoplastic Polyurethane), which means it's rubbery (has good grip), transparent and has a resistance to oil, grease and scratches. The bezel has a 1.1mm lip which lifts and protects your screen when placing it face down on a flat surface. The cut-out holes for the power and headphone jack ports are large, so you should have no trouble fitting in whatever branded plugs you have. There's also cut-out holes for the camera and microphone on the back, which are perfectly sized, and the case also mirrors the Motorola logo dimple on the phone itself, which is a nice touch.
So far I honestly haven't had a single problem with the case at all (hence my five stars), so if you're buying your first Nexus 6 case I'd personally get this one 'cause it's perfecto!
