[T-Mobile LG G2x] mmapcpro:
I just received mine in the mail. I don't know how I feel about it yet, so I'll just post observations.

1) The holster appears to be of much cheaper quality than my Seidio holster.

2) The holster is dimensionally similar to the Seidio, and in fact, the same cases that will fit in my Seidio holster also fit perfectly in this holster (seidio surface, nillkin cases, and this new aquaflex case).

3) The pictures showed being able to insert the phone with the case into the holster with the screen showing, as well...However, there is no possible way to do this without damaging it, that I can see. I needed to take the case off in order to insert the phone into the case that way (with the case off, it does fit well with the screen facing you).

4) The belt clip has a neat "kick-stand" feature, by snapping the clip into the plastic tab. You can also adjust the angle that the phone will sit facing you. However, make sure you have battery life, because you are unable to plug in a charger while it's in the holster.

5) The HDMI output is not blocked by the holster (Seidio holster covers the hdmi output). I suppose this could be useful if you intend on hdmi mirroring a presentation or something. Limited, but potentially useful, feature.

6) The flex case goes on easier than any other case I have, by far...and I have 8 of them now...it simply pops right over the phone. However, the removal of the case is among the more difficult of all my cases. It is even more difficult than my Trident Aegis...the only reason I would rate it easier to remove than the Aegis, is that it is 1 piece, rather than 2.

7) I can see that it will take me getting used to the buttons. They are covered by the case, but they do have a molded form to them. So on the case, the power and volume buttons feel as they do on the phone. However, sometimes when you push them in, the case dampens the "click" you normally would feel. So it just feels different. It is just as responsive, and doesn't seem to require any more effort to push than without the case, but it does feel different, and will take me getting used to it.

8) The case has a good feel to it. Does not have that gel quality that snags on your pocket liner.

9) It is dimensionally almost identical to the Seidio Surface case. Slightly bulkier than the Nillkin cases, but definitely provide more protection.

10) The color scheme of this case seems to match the G2x very well.

11) The seam line from the molding process is definitely visible, and someone raised. In two spots on mine, there is excess material. I think I can trim that down pretty easily with a blade.

12) The screen protector feels pretty smooth. It seems a bit thicker than I would like, but the cutouts are perfect. It is, however, of the narrower variety...narrower than the protector that came on my phone from T-mobile. I will not be installing this on my phone.

edit: I just discovered that I can sit my phone (with the case on) in just the bottom lip of the holster, and adjust the "kick-stand" back to the deepest decline and the phone will be facing me at a proper angle for watching video in landscape mode. This is definitely a plus, because I didn't want to have to take the case off during the day (unless I have to battery pull, but that has become basically non-existent since I started using Trigger 2x rom). BTW, this can also be done in portrait mode...but is somewhat less stable (you have to touch the screen softly).

another edit: If I can obtain another camera to take some good pics, I'll take pics of what I'm talking about so it's easier to follow what I'm describing.
