We use them for our camper. We've written down different tasks to complete before we tackle each one, and while we're parking we'll smack them on the steering wheel. We will not remove it from the steering wheel until the task is completed. It lets us remember important vital steps like put the jack away, turn off the power etc which seems like common sense but sometimes you are in a hurry or routine or 2 people are preparing and you don't know what the other one is has made. They work really well, stay in place and I love the bright colors.
