A13 Photographers Multi-Tool 5-32 (4mm) Allen Wrench Hex and Flat Head Key Chain

The idea of the tool and highly recommend it. However, I should note that while it is fairly easy to torque tightly, do you need a little more pressure when you were trying to unscrew anything. Cannot torque it as tightly as using the standard wrench. That being said, still a very useful tool to easily carry with you,

Works great small and handy.

What a great tool to have in your camera bag.

Great tool for your keychain or strap.

Convenient size. Lost my first one when I lost my keys, so useful I had to replace it.
