Great selection, nice case, but tolerance too high

What I've been looking forward to this case. He was well stocked, really all the important tools were there. The case is also sorted stable and logical. The KO criterion came to the use. Myself am mechatronics industry and worked daily with Hazet and Gedore. For home use, I thought, at least, this suitcase is sufficient. Have a canopy bolted and took the 13mm foot wrench to tighten the hex bolts. The open-end wrench wobbled so that was the screw when tightening almost round. In the 13er nut was no different. Then I took various nuts and combination wrench with the company and measured with a certified and audited digital calipers and a whopping good 4/10 mm (almost found half a millimeter game. That is, the 13mm open-end wrench, as well as the nut actually 13,4mm were wide. For the other operations it was no different. So I have the case sent back (because of the risk of injury in tough screw cases) and thanks to Amazon get my money back on time. Thank you.
