I just received that dock yesterday. First impressions are very good. One small exception.
I use the Platinum case that I got at Best Buy, which is essentially the same as the Seidio case.
The phone docks fine, but the case causes the phone to "tilt" a bit to the left. Even with the sleeve out of the dock, it still tilts a bit and does not seat all the way.
But it is barely noticeable and the dock works great.
If you get this dock, be advised that it does not come with a microUSB cable for connecting the dock to your 12v supply in your vehicle. But if your former phone was an EVO 4G like me, you probably have many of those cables laying around any way.
If you do not use a case, however, with the sleeve in the phone fits like a glove.
If you have seen or used the Seidio dock for the OG, like I did, the first thing I can say about this new dock is even though the EVO LTE is larger than the OG, the dock is less intrusive on the windshield.
