The Bordo Granit X-Plus is a good and correct huge, heavy lock, but it has to be you now, if you want higher security. In general, I am very happy because I've been using it mainly for cutting off my expensive bikes in the basement, because I want to give thieves no chance. For traveling, I use rather the Abus Granit X-Plus padlock, which received very good test results, and even a 12mm cable lock. The Bordo is here by his emenses weight pretty unwieldy. If you are not careful then pops the lock cylinder (possibly even with keys) quite ugly to the frame or to another location - which then hurts for your bike. A quick shut off is not really or I put myself too stupid to .. Especially whom you unpack it once, unlock, unfold, and then depending on how you fixed the bike, still attached by wheel, frame and Latene / fence needs. I've done it five times, it was enough for me. But on the whole it was a good buy, I do not regret, because I'm playing it safe now. At least I feel that way. Because professional thieves could break even this, I suspect.
Buy recommendation for those who need a heavy, legally secure lock. But it is not very handy, or you have to practice a little handling.
