Great tool, good case, high-quality Steckschlüsselsatz
The case here is a good offer. Tool and case are well made and make a stable impression. The case is really a aluminum case and no plastic that looks just like aluminum! The socket wrench set (580-SD-20) was indeed praised some length on Amazon.
I would recommend this case to anyone who is on quality and want to use the tool for years.
Well, I think that the ratchet set is supplied separately in a sturdy case and is not fixed as in many other cases in a foam insert in the base case. So it does not ruin the aluminum case in the garage with oily nuts at the car bolts and the lower luggage part is therefore also otherwise usable, eg for drills and cordless screwdriver set.
So the case is still expandable and can be expanded with additional tools and additional tool plate.
