To preface my review I am just an amateur cyclist who enjoys working on his bike. As such, having a tool box like this is definitely not essential, but it does make working on my bike a lot more enjoyable. I live in an apartment building, so I appreciate being able to take all my tools with me to the garage or balcony where I work on the bike. The tool box has two pallets which fit all the essential tools. The larger bottom part can be organized in various ways - I store my torque wrench, hammer, cassette removal wrench and derailleur hanger gauge there, and they all fit nicely.
