the issue I see with them is that they only fit devices 3" wide. The g2 is 3" exactly, but I use a TPU case with it. Do you think it would still fit?

I have one from the same company, but a different model. When fully expanded, it's got about 3/4" of extra space when I insert my case-less MotoX 2014. I really like this one as it's low profile & sticks to my dash really well.
