What Stock Custom ROM do you use?

Please answer in the following format.

1. What Phone are you using.

2. What ROM are you using.

3. What doesn't work? (THIS IS THE MOST IMPORTANT QUESTION!)

4. What are some of the good things about the ROM.

5. Describe the connection speeds and battery life?

6. Any other things people should know? (like performance, etc..)


Aside from general curiosity, I'm asking this question because I'm in the market for a new phone (and possibly another blet) and I want to see how Stock ROMs perform on non-nexus devices.
