Tools of all sorts are welcome. They include hand tools, power tools, automotive tools, welding, etc...
10x cheaper than the original. Likely not Wera quality but probably not 10x worse either. I've been quite happy with the other Parkside tools I've got.
It's most likely a difference in steel. Cheap steel fractures and wears down, but if you're only using it once a month or a year, you can probably get by. If you're using it every day, it probably won't work for you.
As the saying goes, buy the cheapest tool you think you need, and if it breaks, buy the best. I've had some Lidl tools for a decade, and I used only a very small portion of them to the extent where they broke. And even among them, if I just wore them down (interchangeable tips for my screwdriver), I just ended buying the same.
