I've had quite a few castles and was the most dissatisfied sometime. The Kryptonite Mini is at least now the times, with the highest subjective sense of security to the user. Defiant and strong, small and inflexible, so it works. And indeed it can be in the back jeans pocket carry, though not permanently or at Ner tour through the Odenwald. For my singlespeed wheel size fits quite well, even though it is more of a gamble, even to fix a rail / pole wheel so, but I'm usually not the patience, the scope of the arch is after all quite low , What really bothers me and what I had already in other castles, this Hakelei is the key. Time he turns on properly, then you have to poke around five minutes and nothing moves. Of course, whenever you're in a hurry. It is also not clear why the key sometimes better sitting, but at first it was usually faster. Now after three months and to gross weather I Hakle routinely. Lubricated I have all before, but that does nothing. Constant jerking creates most likely remedy, but one comes thereby somewhat goofy before. Therefore deductions in the B (edinungs) -note.
