I received mine on Tuesday and have been using it since. I like it, mostly. First thing is it feels slicker than my CruzerLite case and I am worried it will slide out of my hand (thus far it has not). It also has less bulk than my Cruzerlite which is neutral for me.
Downsides, the lip on the front is way smaller than the CL and makes me very worried that a face down drop will not protect the screen.
There is a pro and a con for me on the kickstand. It is nice to use watching video, but because of the position of the kickstand I can not effectively use my car mount any longer. It has a button, that when the Nexus4 is put into the cradle, engages the clamps that hold it in place. Because of the kickstand being raised more than the rest of the back it never really hits the button without a bit of effort and even then does not sit quite right.
It is also over twice the price of a CL.
In the absence of working in a job where I spend much of my day on a lift 30 feet in the air (and I have dropped my N4 from that height in my CL and it survived intact) and my auto mount I would take the Seidio over the Cruzerlite.
