Benefits: If you're servicing a MacBook Pro, this is the tool you NEED to remove the display hinges. The tool is ideal for screws and can loosen screws due to the extremely high torque applied to them. during installation. I broke several other cheaper tools trying to remove the same screws. Cons: Mine didn't have the handle pictured. However, it fit perfectly in the handle of another screwdriver I already had, so it didn't matter. For my purposes, I used a 1/4" socket and small socket wrench to turn this bit. Conclusion: Repairing a MacBook Pro or similar? You need this tool. I would give 5 stars if the pin pictured included, this could have been an oversight on Revane's part.
