Reliable controls are the best part for me. I set limits and it helps me feel comfortable handing a card to a driver. I have not had surprises when I review the purchases later. The transaction reporting is useful when I am checking a specific stop and amount. My only nit is it takes a few taps to get to the exact view I want.
Reasonable controls, uneven learning curve. I appreciate being able to set basic spending limits, which helps me feel more in control. However, the initial setup was not very intuitive for me.
Rewards are a nice little bonus. I use the card regularly and it is cool seeing the rewards add up without me thinking about it. Nothing fancy, just a good extra.
Decent network, but not perfect. I like having plenty of places to fuel with the card, but I still run into stretches where it is not convenient. I am not great with apps, so I just go by what I see on the route.
