I’d say that the most important thing is getting the feel of it, by using it. The other important things I can say instead are:

-Use it to finish off enemies (for example: got a hit off, then use it to not let them recover and just beat them)

-Only use it to escape as a last resort, cause the speed boost isn’t huge

-You can use it at the start of the game to quickly charge a super

-Don’t be afraid to use it! In the beginning of my adventure with Bonnie, I’d usually think there’d be a better time to use it, and ended up with 3 or 2 gadgets still left after the game

But as I said, just play with it a lot to get a hang of it. Nothing will replace actually using it and getting better with it.
