I am debating as to whether to get one that mounts to the A/C vent but I am concerned about it being flimsy and possibly damaging the vent. I also own a Honda Fit which has a VERY extended windshield that is quite far from the driver. I could also use a cup mounted bracket as well. 1. Anyone have problems with the "universal" brackets that basically grab just about anything and squeez it to hold it? 2. Anyone have problems with a vent mount? I live in Florida and also don't want to losE much A/C! 3. Is there generally one brand that most people consider the best quality? THANKS!
