The long end of the hex keys is spherical, so you do not necessarily have to rotate the axis exactly parallel. Very good, I like the creak with their ballistic protection, which is achieved via the red button on the ratchet head.
The steel quality is good, none of the tools is to use common hitherto damage appreciable wear etc ..
Even at the regular rate I would say price / performance are absolutely OK (so costs 1 part still only 1 Amazing that this is feasible at this price.).
On suitcases however annoying that necessarily must lie with the half in which there are the nuts on the ground before you open it, otherwise the entire contents fall out (I had several times the pleasure). For transportation always has a foam mat (not shown) are inserted between the two halves, because this otherwise fall all the parts at once. However, one must also say that you can invest the money for the complete set without major problems alone for an empty toolbox.
Therefore: for home use and the case is alright.
