I liked the idea of a kit like this, but it's just not executed well.
The case itself is made of some nice leather, soft to the touch, which is nice. However, I primarily bought it to have all of the needed hex keys and some measurement tools for action. It does not have the one hex key I really needed though, which is the one for setting the action (bridge) of my Fender American Stratocaster. The smallest hex key simply does not fit in the screw hole, which makes it useless to me.
Next, the string action ruler is made of metal and has very sharp edges which I realized when I made a visible scratch in the finish of the guitar while flipping it around.
The screw drivers and the string action ruler are near impossible to get out of their holders/pockets which has pissed me off every time I needed them.
When I received the kit, the polisher spray was not completely closed/tightened at the head, which had resulted in all of the interior of the case having been smeared in the oily liquid.
I would not recommend this kit.
