Here's a prior thread on the FlyGrip:

Page 2 of that thread includes a video I shot and my comments on it. I don't use it all the time, but I still like it a lot and I'm glad I have it.
The FlyGrip works with my ProClip car mount, which I also like a lot, photos in this thread:

ProClip sells a mount that has a built-in charging dock, too, but I bought the simpler and cheaper one that doesn't include that. (I can plug a cable into my phone while it's in my mount if I need to charge it. The ProClip will not work with any case on the phone, however. For a while I wasn't using any case, but I bought a cheap TPU case and cut out a rectangle where the FlyGrip is attached to my phone, so now I can put that case on or take it off (to put the phone in the ProClip in my car) while the FlyGrip stays stuck to my phone.
I think the FlyGrip comes in small, medium, and large sizes, for different size hands. I got the large, and it just barely can work as a kickstand in portrait mode for the GN2 without the phone tipping over. Even then, it doesn't really click into place in portrait mode, so any little bump and the phone would fall over. I understand that the small and medium size FlyGrips as they were originally made (before huge phones like the GN2 came out!) would NOT support the GN2 in portrait mode, so FlyGrip is in the process of redesigning those sizes of FlyGrip (or maybe it has already completed that, I'm not sure) to work as kickstands in portrait mode with big phones.
I mounted my FlyGrip much lower than shown in the QBKing77 video shown above. I suppose if it were mounted up high like that on the back of the phone, it might not topple over when used as a kickstand in portrait mode, but the phone would be reclined at a pretty low angle, too.
I do like using the kickstand in landscape mode if watching a video.
Finally, not sure if this deal is still live or not, but when I bought mine, you could enter QBKing77 as a promotion code and get free shipping on a FlyGrip.
