I would say that what I bought was probably not the "super wonderful, high, German quality" tool that the $800-1100 dollar tool is...however...it was very nice. The tooling on it was good, the finish was nice, and the blow molded plastic case it came in is actually of good quality, not flimsy as I expected. I actually was very pleased with the tool, it worked very well, smooth and no binding on compression or release. I have used it 4 times and not even once felt as if it was dangerous or of a quality that might fail. It is your choice. I paid about $250 for it shipped, I am very pleased with it and it does not get industrial shop use so I trust it, I trusted it with my life using it 4 times I guess.
It is your choice, use the wrong tool, use no tool, use a "NON-German made" tool, or pay $900 or more for a tool you will use a few times. Oh, maybe someone will rent you their $1100 tool for a week or so, try that too.
