Customer Reviews

Strong, heavy, big
The lock looks very strong, with an oversized diameter shackle and a oval section main body with central key location, the action locks both sides of the shackle "U" not just one like some models, the keys are high security not the tubular type which can be easily opend with a pen, one key of the 3 has a blue LED light built in, though the carrying bracket is well made I found the lock was too big to fit within the frame of my 19" framed MTB so is unlikely to fit most bikes. A note on the £1100 theft insurance you have to register the lock with kryptonite within 2 weeks and if your bike is stolen you have to send them the broken lock to claim!

Yep, another good lock rubbish key one
Having read the warnings of 'good lock, rubbish key', I was very careful with my key, so it lasted a full three weeks before breaking. On the bright side, I can send the lock back free of charge and get another one, although in that time my bike may get stolen.

okay but rusts
Bought this item about a month ago.
Its a pretty solid lock so, as you would expect, it weighs quite a lot.
The only real unexpected problem was that it started rusting up. The rain gets in even with the key hole slider shut. I'm trying wd40 on it so I'll have to see how it goes.
Not that impressed so far.
