I do and I have never had to take another car because my LEAF wasn't charged enough in the morning. I drive around 55-60 miles per day and only charge to 80% most of the time. I get home at around 9PM and charge through to the morning and leave at around 10AM. That's enough time to get me to 80% well before I leave for work. I can usually make it to 100% too, but there have been some occasions when I let the SOC drop too low and I couldn't get the full 100% by the time I left.
I occasionally opportunity charge at work simply because it's free, but it's not absolutely necessary in the summer. It will also probably be a necessity this winter since 60 miles is tough to do in a LEAF with a battery pack that is almost frozen.
The biggest negative in trickle charging is having to plug in and unplug and move the EVSE around. My car is only a few months old, but my EVSE looks like it's been through hell. But it's still MORE convenient than having to stop for gas every 4 or 5 days with my old gas car.
