I bought this for $5 from eBay shipped. Ordered it Saturday morning; it arrived on Wednesday. (I searched for US-based sellers to avoid delays.)
Is it the "best"? Probably not, but most cases (and accessories in general) are such a total ripoff. 20 cents to make and they get sold for up to $15. It looks just like the "Cimo S-Line Back Case Flexible TPU Cover for Google Nexus 4 (LG E960)" selling at Amazon for $8.93 and the "i-Blason Slim Fit S Line Flexible TPU Case for Google Nexus 4 Smart Phone E960 LG" selling for $12.95. The baggie was labeled "Zizo" but it's just the company that bought from the same commodity case mill the others bought at. I bought a Body Glove case for my OG EVO 4G in 2010 and it was $20 and so flimsy it broke in one place and I had to Scotch tape it together.
I ran my GS2 naked, but the Nexus 4 gives me the willies setting it down on that glass back and with my dry hands, it's hard to keep a grip on the slick glass. The "ridges for her pleasure" should help prevent the easy slips and the lens is protected on its back and the screen when set face down.
