Pros: I love the drill bits and it's great that there are dual wrenches in multiple sizes. Great quality at a great price. Cons: There is nothing in the case to hold the bits so they fall out and slide if you turn it upside down or it bounces up. It could have been better to be honest, maybe if there was a way to snap the bits in or redesign the case a bit so there wasn't that much room to slide around. When I'm building at the end of a project, I want to be able to just toss it in a toolbox so everything in it doesn't get mixed up.
