Mine doesn't launch enough. I have been so frustrated that I've screamed "OKAY GOOGLE NOW!!!!" at it and it does NOTHING.
I've re-recorded it. I wish it were more sensitive. I get the "It's noisy please speak up." often. That will be with the radio on, the air conditioning blowing and the Maxx in the drink cup holder.
Then I turn down the blower, turn down the radio and pick up my phone and I STILL get that same message.
Oh well, 1st generation technology and 1st world problems.
