A check with a Difficulty Class (DC) of 10 or less is not something that you should be making your players roll. The DC 10 represents an activity that is done regularly that poses no real challenge to your average person conducted under normal circumstances. A DC that is set at less than 10 represents something that an average person could do with little to no trouble, like changing the channel on the remote or picking up a glass of coke.
Now I know that to some of my regular readers that this probably shouldn't have needed addressing but you would be amazed at how many comments I've read today while I was researching wilderness survival where people kept championing the "Roll every DC, no matter how low," line of thought. And I get it, they've got no one who will play in their boring ass games so they want us to have the same experience.
Don't make people roll for things they should automatically succeed at doing. It slows down the game. It makes you a boring, unimaginative Dungeon Master. Forget that noise and keep the game moving.
