The product adheres quite strongly that one can say, but it does not have the specified strengths.
The first thing I could find out the tensile test, the tears of this band very quickly. (Belt not kinked or twisted !!!)
Through the tensile test could be seen also that largely lacks that known by duct tape strong fabric and the rubber layer is very thin. The largest share was the glue. He resembled a double-sided tape.
And this impression made on full-width wide at me. A double-sided tape, the only a very light mesh was applied from binding threads, which is plated with a thin layer of rubber and inferior.
A clear China (armored) tape! Insufficient and definitely not comparable to German quality standards with the original product of the German Federal Armed Forces!
For those who rely on a high-strength duct tape, should take the old familiar, held in Olive tape. (There is also here at Amazon!)
Since the tape does not match the original, known federally duct tape, the actual namesake, this gets only 1 star here! Because it is not "extra strong" nor "duct tape". - I have my role also sent back!
