Just an update I got the Incipio Feather case for Christmas and with the extended battery it does not fit, if you take the back off the phone it works well, It actual didnt seem to fit even when I put the standard back on the phone for some reason.
I had no problem putting the Defender over the extended battery but I will say the quality of the Defender case for the Nexus doesn't seem to be the same quality it is for my wifes Iphone.
does this case fit with the extended battery? And regardless of it fitting, has anyone used this case? Is it a bit flimsy where you can pull at the rubber part of the case?
