One thing you will notice when you get the packaging is that, well there isn't much to say as its in a plastic wrap, with a cardboard cutout placeholder for your phone. They spent the money were it needs to go; on the case itself.
As expected from Diztronic, the case is a built top notch using a soft but firm flexible TPU material. It has a two tone appearance where the edge/frame is a shiny glossy black (along with the Diztronic logo on the back) where the rest of the case is a soft grippy matte black on the back and sides. A thing to point out is the nice feel the matte finish has. It almost feels like the Nexus 5 back without a case. It just feels good. One thing I like is that Diztronic did not plaster their name all over the case like some case manufacturers do. Just one simply logo at the back near the bottom.
The cutouts are all in the perfect location and aligned right. The cutouts for all ports/mics/speakers are spot on. One thing I would like to point out is the cutout for the headphone jack. It's bigger than other cases I've seen and I like that. It allows for headphone plugs off varying sizes to be used with our phone. Many times a plug will be too big to be used with certain cases and the phone would have to removed from the case to use said plug. The cutout is a large nice square cutout. So thumbs up to Diztronic for that. Also, the microusb port cutout is large also, allowing for oem and aftermarket micro usb plugs to be used. Which is really like as I have plugs and charges of all sorts of sizes around the house, bag and car.
One thing that did differ from the S3 Diztronic case is that there is no cutouts for the buttons; volume and power. I'm sure a lot of us went the super cheap route before and got a tpu case off of ebay with no cutouts and it was just plain misery trying to press the buttons. That was one of the big pluses for me on the S3 case and was doubtful and wary about no cutouts on the Nexus 5 case. Yet, Diztronic has pulled through and made pressing the buttons easy and nice even without the cutouts. The fake buttons on the case to mimic the buttons on the phone are very nicely designed and implemented. They actually look and feel like real buttons and not just some bump on the case like the cheaper tpu cases.
Another thing I liked is that the edges are raised to protect the phone if you place it face down on the table. So no scratching the screen when doing so.
Also, unlike the slim cases from Spigen and Ringke (other cases I considered) is that it has decent protection all the way around the phone. The slim cases protect the sides but not so much the top and bottom. Sure its a little bulkier and thicker but my mind is a little more at ease with the added protection.
