Bought as a companion piece for my little tool wallet my tool bag. In the middle of my little fits prima Bosch drill plus boxes with drills, Wago terminals, laser meter, flashlight and a number of small parts. In the two outer flaps fit many tools in the interior and side pockets have a rest. What I do not like that? As would be the weight of the bag. Empty it is quite difficult. Whether that must be so, I do not know. If you have mold in it, it is really difficult. What I still do not like, is that start after a relatively short period of use, the zippers to hook. That's not a problem, but somehow annoying if you have to do quickly. Otherwise I have no major complaints and I am happy - to be able to take much - despite weight. Even with the classification of the subjects I'll be fine after some pondering. The strap, the (probably thanks to weight) is very robust and even revealed no weaknesses, wearing the bag is really quite pleasant. Also on hand-carrying straps you can not complain. Anyway, I put the bag a suitcase always in front, because they can be easily super store, even if time is not a place. That's when an inflexible suitcase not so nice.
