I've always been a fan of flip cases that protect the entire phone, including screen, while providing very good protection against falls. This is quite satisfactory for the Nexus 5: the materials are of good quality and leaves a good impression to the touch (a little less smell). The release for the camera is sufficient and does not interfere with flash.
Side small defects, note the lack of visualization of the notification LED hole, you can do yourself with adequate clamp, and the lack of access hole USB jack, open the valve to connect the phone.
More troublesome, keeping the phone does not inspire confidence, I fear it leaves the hull in case of fall. I have remedied the Patafix.
