"The main advantage of a roll is that they pack smaller and flatter. They also don't clank around as much as a fully loaded toolbox. I keep a roll with zippered pockets in my car because it's old and living on borrowed time, and I've found that the combination of a tool roll with some basic organization tools (like socket rails) allow me to neatly roll it away under a seat and keep things organized enough to not be frustrating. The main thing I recommend is familiarize yourself with what you're going to be working on and build out your tools around it (I have a Japanese truck and motorcycle, so I rarely carry any SAE tools, etc.) "

"Maybe it's an excuse for Apple to sell $150 anodized aluminum wheel chocks."

"Upvoted for selfish reasons (I went there)."

"Why not just grab the side rails of the seat? Those look like they'd force you to twist your wrist at an awkward angle to use them anyway."

"They mostly just keep the bowls from traveling around a slick floor. I have a small kitchen and it helps keep things tidy."
