I'm a beginner at assembly and it took me hours to put this together and I've only done it twice. Definitely harder to crack than a Chinese 10D Master Lock clone. It is also manufactured to much better tolerances. However, I believe it can be opened instantly with a tool that pushes all the pins far enough (I don't have that tool so can't try it). It's also a very light, thin, thin feeling. Using brute force and tools that fit in your pocket I'm sure this can be done quickly, either with hand bolt cutters or the key lever method.
