Since I always had the problem to see many keys in a drawer disorganized the right, I opted for this set in the rolling bag. Impeccable and mainly falls equally on what is missing, and we find the right size right away. Even more stringent conditions (dirt, work with lever wg. Higher power, etc.) make the set of anything. As for me, the very often what has to screws and repair and build optimal, mainly because the wrench sizes 6-32 mm cover everything one, garage, etc. needs so the house, garden. When you're done, simply tuck and roll bag again, and already everything is tidy.
