Screen protectors - just fit display part of front glass, not edge to edge. So they suck, but I got them to hold me over until I get something better
Snap On Hard Cover - the case itself is good, but not right for this phone. After adding the case I find the phone to be too bulky. I have large hands too.
Car Dock - Happy with it. The unit locks into place very well. Feels very sturdy although I can't seem to get the base and clip to lock together it doesn't present a problem. You can leave the car charger connected to the dock which is nice. Once you click your X in it charges.
Desk Dock - It works as you would expect. Solid build. However I am getting a widget error that doesn't seem to be impacting anything, just annoying to look at.
EDIT: If you get this widget error on the Desk/HDMI dock it is because there is no city set for the weather widget. Just update with city or delete/add and you'll be prompted for city. (Thanks to JhankG)
